    If I could have any superpower, it would be the ability to travel through time. This extraordinary talent would be a bridge to understanding the past, optimizing the present, and shaping a brighter future. Time travel wouldn’t just be an adventure; it would be a tool for tackling some of humanity’s most pressing social issues. Here’s how I would use it:

    1. Addressing Historical Inequities

    Imagine going back to pivotal moments in history to prevent wars, resolve conflicts, or steer societies toward more just decisions. By averting atrocities like genocides or colonial exploitation, we could rewrite narratives of oppression and build a foundation for equality and peace.

    • Example: Preventing moments of exploitation during the industrial revolution, ensuring fair wages and humane conditions, and influencing early labor reforms.

    2. Solving Modern Challenges with Historical Wisdom

    Time travel would allow me to bring forgotten solutions from the past to address present-day problems. Ancient cultures often held insights into sustainable living and community harmony that have been lost over time.

    • Example: Reviving traditional farming techniques to combat food insecurity or adopting ancient water management systems in drought-prone areas.

    3. Providing Early Warnings

    I could visit the future to identify environmental, economic, or social catastrophes before they occur. Armed with this foresight, I could work with scientists, leaders, and communities to prevent disasters and reduce their impact.

    • Example: Stopping climate change by warning past societies of its dangers and advocating for renewable energy centuries earlier.

    4. Empowering Marginalized Groups

    Traveling back to moments when marginalized voices were silenced, I could amplify their messages and influence progressive changes. Ensuring women’s rights, education for all, and freedom from discrimination would accelerate societal progress.

    • Example: Supporting activists like Rosa Parks or Malala Yousafzai earlier in their journeys to strengthen their movements.

    5. Bridging Generations

    Time travel could foster understanding across generations, creating empathy and unity. By bringing people face-to-face with their ancestors or future descendants, I could inspire them to value their heritage and act responsibly for future generations.

    • Example: Showing policymakers the long-term consequences of their decisions on future societies.

    6. Creating a Knowledge Repository

    With time travel, I could collect knowledge from every era, ensuring humanity doesn’t repeat its mistakes. This repository would act as a guiding beacon for innovation, ethics, and cooperation.

    • Example: Safeguarding lost manuscripts and technologies to inspire modern breakthroughs in medicine, energy, and education.

    7. Inspiring Global Change

    Through small but impactful interventions, I could create ripple effects that reshape the world. Whether it’s a word of encouragement to a future leader or stopping a misguided policy, the potential to create meaningful change is limitless.

    • Example: Preventing key events that led to prolonged conflicts, like the onset of World War I.

    The Ultimate Goal

    This superpower wouldn’t be about controlling or dominating time but about healing the wounds of humanity and nurturing a harmonious future. With time travel, I’d strive to be a guardian of fairness, a protector of the planet, and a catalyst for unity.

    In the end, the power to travel through time would be a reminder that the past, present, and future are interconnected—and that by understanding one, we can transform them all.

    pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution. Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being.Ocean pollution has many causes, including:
    Nonpoint source pollution
    This is pollution that comes from many small sources, like vehicles, septic tanks, farms, and livestock ranches. It’s often caused by runoff, which is when rain or snow carries pollutants from the ground to the ocean.
    Point source pollution
    This is pollution that comes from a single source, like an oil spill or chemical spill.
    Plastics
    Plastic bags are one of the most deadly types of plastic in the ocean because they can be mistaken for food by marine life. They can take up to 20 years to decompose.
    Offshore drilling
    The oil and gas industry’s operations can lead to spills, which can cause irreversible damage to marine ecosystems.
    Ocean acidification
    This occurs when the pH of the ocean lowers, which can have harmful effects on marine organisms.
    Air pollution
    Some water pollution starts as air pollution, which settles into waterways and oceans.
    Other pollutants
    Other pollutants include:
    Chemical runoff
    Crude oil
    Sewage
    Fertilizers
    Discarded fishing nets
    Noise from shipping and drilling

    Cellular respiration is a process that breaks down food molecules to produce energy for cells. It’s a vital process that occurs in the cells of all plants and some animals.
    What it is
    Cellular respiration is a series of chemical reactions that occur in the mitochondria of cells.
    It breaks down glucose and oxygen to produce energy in the form of adenosine triphosphate (ATP).
    It also releases carbon dioxide and water as waste products.
    Why it’s important
    Cellular respiration provides cells with the energy they need to function.
    Without cellular respiration, living things would not be able to get the energy they need from food and would eventually die.
    How it works
    Cellular respiration has three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.
    The reactions involved in cellular respiration are catabolic, meaning they break down molecules into smaller ones.

    The onset of the 13th century heralded the fragmentation of the once-mighty Chola and Chalukya empires, paving the way for the emergence of four distinct kingdoms within the region. To the south, the Pandyas and Hoysalas rose to prominence, while the northern territories saw the ascendance of the Kakatiyas and Yadavas as influential powers. Simultaneously, the Gurjara-Pratihara dynasty was effectively eradicated from the political arena by the invading Ghaznavids in the early 11th century.

    Following the disintegration of the Gurjara-Pratihara empire, no single state emerged to fill the void. Instead, a tapestry of smaller, independent powers took root, including the Gahadavalas in Kannauj, the Paramaras in Malwa, the Chalukyas in Gujarat, the Chauhans in Ajmer, the Tomars in Delhi, and the Chandellas in Bundelkhand, each vying for control and influence.

    The timelines of these dynasties are noteworthy: the Hoysala dynasty thrived from the 10th to the 14th centuries, the Gahadavala rulers reigned during the 11th to 12th centuries, the Kakatiya rulers held power from the 12th to the 14th centuries, and the Yadava rulers dominated from the 12th to the 14th centuries.

    Modernization and Westernization are related but distinct concepts, often confused due to their overlapping effects in many societies. Here’s how they differ:

    1. Definition

    Modernization refers to the process of adopting new technologies, institutions, and practices to improve economic, political, and social development. It is a broad and universal concept that can occur in any society without necessarily adopting Western cultural values.

    Westernization is the adoption of cultural, social, political, and economic norms associated with Western countries (primarily Europe and North America). It involves embracing Western lifestyles, clothing, language, governance models, and sometimes even ideologies.

    2. Scope

    Modernization focuses on technological advancement, industrialization, urbanization, and improved governance. It includes scientific progress, efficient administration, infrastructure development, and better healthcare and education.

    Westernization involves cultural aspects such as wearing Western attire, eating fast food, speaking English, celebrating Western festivals, and following Western entertainment and social norms.

    3. Dependency on Western Influence

    Modernization does not necessarily mean adopting Western values. Countries like Japan, China, and South Korea have modernized while maintaining their unique cultural identities.

    Westernization implies a shift towards Western culture, often replacing or overshadowing indigenous traditions.

    4. Examples

    Modernization Example: India’s use of digital banking, advancements in space technology, and smart city projects without losing its cultural heritage.

    Westernization Example: The influence of Hollywood movies, Western fashion brands, and fast-food chains changing local habits and traditions.

    5. Impact on Society

    Modernization leads to progress in infrastructure, governance, and economic growth, allowing a country to compete globally while preserving its identity.

    Westernization may result in cultural erosion, where local traditions and languages decline in favor of Western lifestyles.

    Conclusion

    Modernization is a global and necessary phenomenon for progress, while Westernization is a cultural shift that is optional and varies by society. A country can modernize without being Westernized, but Westernization often accompanies modernization due to globalization.

    Key Difference

    Term Whitespace Unicode Space Character

    Definition Any character that creates “blank” space in text (invisible characters that separate words or lines). Specific space-like characters defined in the Unicode standard.
    Scope A broad category that includes a variety of invisible characters like spaces, tabs, and newlines. A subset of Unicode characters that are defined as various types of space.
    Examples ‘ ‘ (space), \n (newline), \t (tab), \r (carriage return) U+0020 (Space), U+00A0 (No-Break Space), U+2003 (Em Space), U+2009 (Thin Space), etc.
    In Java / Programming Identified by Character.isWhitespace() Each Unicode space has a specific code point, width, and behavior in rendering.

    1. Whitespace Characters

    These are general characters that create space but are often interpreted by programming languages or parsers.

    In Java, Character.isWhitespace(c) returns true for:

    Standard space ‘ ‘ (U+0020)

    Tab \t (U+0009)

    Newline \n (U+000A)

    Carriage return \r (U+000D)

    Vertical tab \u000B

    Form feed \u000C

    All Unicode characters categorized as whitespace.

    2. Unicode Space Characters

    Unicode defines many space characters explicitly, each with a specific purpose or width. Here are a few notable ones:

    Unicode Name Width/Use

    U+0020 Space Standard space character
    U+00A0 No-Break Space Same as space but prevents line breaks
    U+2000 En Quad Space equal to 1 en
    U+2001 Em Quad Space equal to 1 em
    U+2002 En Space Narrower than em space
    U+2003 Em Space Wider space for typesetting
    U+2009 Thin Space Very narrow space
    U+202F Narrow No-Break Space Narrower than no-break space
    U+3000 Ideographic Space Used in East Asian scripts, full-width

    These characters may not be detected by simple string manipulations unless Unicode-aware methods are used.

    Important Distinctions

    All Unicode space characters are whitespace, but not all whitespace characters are Unicode space characters.

    Some whitespace characters (like \n, \t) are control characters, not printable spaces.

    Unicode spaces may have width, non-breaking behavior, or typographic purpose.

    Summary

    Concept Includes

    Whitespace Spaces, tabs, newlines, form feeds, etc.
    Unicode Space Characters Precisely defined space characters like U+00A0, U+2002, U+2003, etc.

    Vaccines stimulate the immune system by mimicking an infection, training the body to recognize and combat specific pathogens (viruses, bacteria, or toxins) without causing the disease. Here’s a step-by-step explanation:

    StageDescription
    1. Introduction of AntigensVaccines contain antigens (weakened, inactivated, or fragmented parts of a pathogen) that mimic the disease-causing agent.
    2. Activation of the Immune System– The antigens are recognized as foreign by the immune system.
    – Specialized cells like macrophages and dendritic cells engulf the antigens and present them to helper T cells.
    3. Stimulation of B Cells– Helper T cells activate B cells, which produce antibodies specific to the antigen.
    – These antibodies bind to the antigens, marking them for destruction.
    4. Activation of T Cells– Cytotoxic T cells are activated to destroy infected cells (if the pathogen replicates inside cells).
    – Memory T cells are formed for long-term immunity.
    5. Creation of Memory Cells– Both memory B cells and memory T cells are generated.
    – These cells “remember” the antigen and respond more quickly and effectively if the pathogen is encountered again.
    6. Immunity Established– The immune system now has a “blueprint” to recognize and combat the pathogen.
    – This prevents future infections or reduces the severity of the disease.

    Types of Vaccines and Their Mechanisms

    TypeMechanismExamples
    Live-Attenuated VaccinesUse weakened but live forms of the pathogen, providing a strong and lasting immune response.Measles, Mumps, Rubella (MMR), Chickenpox
    Inactivated VaccinesContain killed pathogens, which cannot cause disease but still stimulate an immune response.Polio (IPV), Hepatitis A
    Subunit, Recombinant, or Conjugate VaccinesUse parts of the pathogen, like proteins or sugars, to trigger an immune response.Hepatitis B, HPV, Pneumococcal
    mRNA VaccinesProvide genetic instructions for cells to produce pathogen proteins, triggering an immune response.COVID-19 (Pfizer, Moderna)
    Viral Vector VaccinesUse a harmless virus to deliver genetic material for producing pathogen antigens.COVID-19 (Johnson & Johnson, AstraZeneca)

    Benefits of Vaccination

    • Prevention: Protects individuals and communities by reducing the spread of diseases (herd immunity).
    • Training the Immune System: Prepares the body to fight infections without causing the actual disease.
    • Long-Term Immunity: Memory cells provide lasting protection, sometimes requiring booster doses to maintain immunity.

    Vaccines are a critical tool in public health, harnessing the natural power of the immune system to prevent serious diseases and save lives

    The immune system protects the body from harmful invaders, such as viruses, bacteria, fungi, and other pathogens, through a highly organized and complex defense mechanism. It involves a variety of cells, tissues, and organs working together to detect and respond to threats. Here’s how it works:

    Key Components of the Immune System

    1. White Blood Cells (Leukocytes): These cells are the main players in immune defense. Different types of white blood cells perform specific roles:
      • Phagocytes (e.g., neutrophils, macrophages) engulf and digest pathogens.
      • Lymphocytes (B cells and T cells) are involved in identifying and attacking specific pathogens.
    2. Antibodies: Produced by B cells, antibodies are proteins that specifically recognize and bind to antigens (foreign molecules) on pathogens, marking them for destruction or neutralization.
    3. Bone Marrow: The production site of blood cells, including immune cells like white blood cells.
    4. Thymus: The organ where T cells mature and learn to distinguish between the body’s own cells and foreign cells.
    5. Spleen: Filters blood, removing old or damaged red blood cells and assisting in immune responses by activating immune cells to fight pathogens.
    6. Lymphatic System: A network of vessels and lymph nodes where immune cells are stored and where pathogens are filtered from the blood.

    How the Immune System Protects the Body

    1. First Line of Defense – Physical and Chemical Barriers:
      • Skin: Acts as a physical barrier that prevents pathogens from entering the body.
      • Mucous Membranes: In the respiratory, digestive, and urinary tracts, mucus traps pathogens, while enzymes in the saliva and stomach destroy them.
      • Cilia: Tiny hair-like structures in the respiratory system that sweep away pathogens.
      • Acidic Environments: The stomach’s acidic environment kills many microorganisms.
    2. Second Line of Defense – Innate Immune Response: If pathogens bypass the physical barriers, the innate immune system kicks in:
      • Phagocytosis: Phagocytes (like macrophages) engulf and digest pathogens.
      • Inflammation: The body increases blood flow to the infected area, bringing immune cells and proteins to fight infection.
      • Fever: The body raises its temperature to slow the growth of pathogens and enhance the effectiveness of immune responses.
    3. Third Line of Defense – Adaptive Immune Response: The adaptive immune system is more specific and tailored to each pathogen:
      • Recognition of Antigens: B cells and T cells identify specific antigens on pathogens.
      • Activation of B Cells: B cells produce antibodies that bind to antigens, neutralizing the pathogens or marking them for destruction by other immune cells.
      • Activation of T Cells:
        • Helper T cells activate B cells and other immune cells.
        • Cytotoxic T cells directly destroy infected cells or cancerous cells.
      • Memory Cells: After an infection, memory B and T cells remain in the body, allowing for a quicker and stronger response if the pathogen is encountered again (immunological memory).
    4. Immune System Memory:
      • The immune system “remembers” past infections through memory cells. When a pathogen is encountered again, the immune system can respond faster and more effectively, often preventing illness (this is the basis of immunity and vaccination).

    Vaccination:

    Vaccines help the immune system prepare for future infections by introducing a harmless part of a pathogen (like a protein or inactivated virus), which triggers an immune response and the creation of memory cells. This provides immunity without causing the disease.

    The immune system protects the body by recognizing and attacking harmful invaders through physical barriers, innate responses, and adaptive immune responses. It “remembers” past infections to defend the body more efficiently in the future.

    A black hole is a region of space where the gravitational pull is so strong that nothing, not even light, can escape from it. The boundary around a black hole is called the event horizon. Once anything crosses this boundary, it is irrevocably drawn into the black hole.

    Black holes form from the remnants of massive stars that have ended their life cycles. When such a star runs out of nuclear fuel, it can no longer counteract the force of gravity with the pressure from nuclear fusion. This causes the core to collapse under its own gravity, potentially forming a black hole if the mass is sufficient.

    The different types of black holes are:

    1. Stellar black holes: Formed from the collapse of massive stars.

    2. Supermassive black holes: Found at the centers of galaxies, including our own Milky Way, and have masses millions to billions of times that of the Sun.

    3. Intermediate black holes: With masses between stellar and supermassive black holes, they are a bit more mysterious and less understood.

    4. Primordial black holes: Hypothetical black holes that may have formed soon after the Big Bang.

    Black holes are studied through their interaction with nearby matter and the radiation emitted from accreting materials, such as in accretion disks or relativistic jets.

    The necessity of a college degree for success has become a topic of debate in recent years. While a degree has traditionally been viewed as a ticket to better career prospects and financial stability, many individuals have achieved remarkable success without it. Here’s a detailed exploration with examples:

    Why a College Degree Is Considered Necessary

    1. Structured Learning: College provides a structured environment to acquire in-depth knowledge and critical thinking skills.
      Example: Sundar Pichai, the CEO of Google, pursued engineering at IIT Kharagpur and later earned degrees from Stanford and Wharton, which equipped him with the expertise to lead one of the world’s most innovative companies.
    2. Professional Requirements: Some careers, such as medicine, law, and engineering, mandate formal education.
      Example: A doctor or lawyer cannot practice without obtaining the requisite qualifications and licenses.
    3. Networking Opportunities: College exposes students to a wide network of peers, professors, and industry professionals.
      Example: Many tech entrepreneurs met their co-founders at university, like Larry Page and Sergey Brin, who conceived Google while studying at Stanford.

    Why a College Degree Might Not Be Necessary for Success

    1. Skill-Based Economy: In the digital age, practical skills and creativity often outweigh formal qualifications.
      Example: Steve Jobs, co-founder of Apple, dropped out of college but revolutionized the tech industry through his vision and innovation.
    2. Access to Online Education: Platforms like Coursera, Udemy, and YouTube provide affordable or free access to high-quality education.
      Example: Elon Musk, while holding degrees, advocates for self-learning and emphasizes skills over credentials.
    3. Entrepreneurial Spirit: Many successful entrepreneurs bypassed college to focus on their ventures.
      Example: Mark Zuckerberg, the founder of Facebook, left Harvard to build one of the world’s largest social media platforms.
    4. Trade and Vocational Skills: Jobs in skilled trades such as plumbing, carpentry, or programming often value experience and certifications over degrees.
      Example: Mike Rowe, host of Dirty Jobs, champions trade education, arguing that skilled laborers are in high demand and can achieve financial success without a college degree.

    Balancing Perspectives

    While success without a degree is possible, it often requires:

    1. Self-Motivation: A strong drive to learn and adapt independently.
    2. Practical Experience: Real-world problem-solving and hands-on experience.
    3. Networking and Mentorship: Building a support system outside traditional academic paths.

    At the same time, certain industries and roles still prioritize formal education, making a degree essential in specific contexts.

    A college degree is not the sole determinant of success but remains a valuable tool for many. The path to success depends on individual goals, industries, and personal circumstances. Whether with or without a degree, success often boils down to persistence, creativity, and a commitment to lifelong learning.

    Lord Rama is referred to as “Maryada Purushottam” because he is considered the ideal man (Purushottam) who upheld the highest standards of dharma, ethics, and responsibilities (Maryada) in every aspect of his life. This title reflects his embodiment of virtue, self-discipline, and unwavering commitment to righteousness. Here’s an explanation of why this title is attributed to Lord Rama:

    1. Upholding Dharma (Righteousness)

    • Lord Rama is seen as the perfect example of someone who adhered to dharma, even when it meant personal sacrifice.
    • Example: He willingly accepted his exile to the forest for 14 years to honor his father, King Dasharatha’s promise to Kaikeyi, despite knowing it was unfair. This act demonstrates his unwavering respect for truth and duty.

    2. Ideal Son

    • Rama’s respect for his parents and his willingness to fulfill their wishes make him an exemplary son.
    • Example: His decision to go into exile was not out of compulsion but a conscious choice to maintain his father’s honor.

    3. Ideal Husband

    • Rama demonstrated unconditional love and respect for his wife, Sita.
    • Example: His journey to rescue Sita from Ravana showcases his loyalty and determination to protect his spouse, setting an ideal for marital devotion.

    4. Ideal Brother

    • Lord Rama shared a deep bond with his brothers, particularly Lakshmana, Bharata, and Shatrughna.
    • Example: He showed equal affection and respect for all his brothers. His compassion and understanding allowed them to coexist harmoniously.

    5. Ideal King

    • Rama ruled Ayodhya with justice and fairness, prioritizing the welfare of his subjects over personal desires.
    • Example: The period of his rule, referred to as “Rama Rajya,” is considered the epitome of good governance, characterized by peace, prosperity, and justice.

    6. Sacrifice for the Greater Good

    • Rama’s life is marked by sacrifices for the well-being of others.
    • Example: When public opinion doubted Sita’s chastity after her return from Lanka, Rama prioritized the moral code of the time and sent Sita to the forest, demonstrating his commitment to his responsibilities as a king.

    7. Perfect Balance Between Emotion and Duty

    • Rama’s life reflects a balance between personal emotions and social duties. While he deeply loved Sita and was heartbroken during their separation, he never let his emotions override his dharma.

    8. Embodiment of Self-Control and Patience

    • Lord Rama consistently displayed patience, calmness, and self-control, even in challenging situations.
    • Example: He dealt with adversities during his exile with grace and without anger or resentment.

    The title “Maryada Purushottam” symbolizes Lord Rama’s role as the ultimate human being who followed dharma in every facet of life. He serves as a timeless role model, embodying the virtues of honesty, compassion, humility, and selflessness, inspiring people to strive for moral and ethical excellence.

    In cricket, the term “Nelson” refers to scores that are considered unlucky, typically associated with the numbers 111, 222, 333, and so on. These are multiples of 111, and the superstition stems from the belief that these scores resemble a wicketless set of stumps, possibly symbolizing bad luck.

    Origin of the Term:

    1. Lord Nelson Connection: The term is often linked to Admiral Lord Nelson, the British naval hero. It is humorously claimed that Nelson had “one eye, one arm, and one leg” during battle, hence the association with 111. However, this claim is historically inaccurate, as Nelson had both legs. Despite this, the superstition persisted in cricket folklore.

    2. Superstition in Cricket: The belief is that “Nelson” scores bring bad luck, and a wicket might fall when a team or player reaches such a score.

    Practices and Traditions:

    Umpire David Shepherd’s Ritual: The superstition gained more attention thanks to David Shepherd, a famous cricket umpire. Whenever the score reached a Nelson (111, 222, etc.), Shepherd would hop on one leg, supposedly to ward off bad luck. This quirky ritual became iconic in cricket.

    Fans’ Reactions: Fans and players sometimes exhibit nervousness or perform small superstitions when a team or player is stuck on a Nelson score.

    Modern View:

    While the “Nelson” superstition is mostly a light-hearted tradition, it remains an entertaining and quirky aspect of cricket culture, highlighting the sport’s blend of historical anecdotes and superstition.

    For every non-negative integer \( n \), the square root \( \sqrt{n} \) is either an integer or an irrational number.

    Proof (by contradiction):

    Suppose \( \sqrt{n} \) is rational but **not** an integer.

    Then there exist integers \( a \) and \( b \), with \( \gcd(a, b) = 1 \) and \( b \ne 1 \), such that:
    \[
    \sqrt{n} = \frac{a}{b}
    \]

    Squaring both sides:
    \[
    n = \left( \frac{a}{b} \right)^2 = \frac{a^2}{b^2}
    \Rightarrow a^2 = n b^2
    \]

    This implies that \( b^2 \) divides \( a^2 \). But since \( \gcd(a, b) = 1 \), it follows that \( \gcd(a^2, b^2) = 1 \) as well. Hence, the only way \( b^2 \mid a^2 \) can be true is if \( b^2 = 1 \), which means:
    \[
    b = 1
    \Rightarrow \sqrt{n} = \frac{a}{1} = a \in \mathbb{Z}
    \]

    This contradicts our assumption that \( \sqrt{n} \) is rational **but not** an integer.

    Conclusion:
    If \( \sqrt{n} \) is rational, then it must be an integer.
    Therefore, if \( \sqrt{n} \) is not an integer, it must be irrational.

    \[
    \boxed{\text{For all } n \in \mathbb{N}_0,\ \sqrt{n} \in \mathbb{Z} \cup (\mathbb{R} \setminus \mathbb{Q})}
    \]

    A brain stroke, also known as a cerebrovascular accident (CVA), occurs when the blood supply to a part of the brain is disrupted, leading to brain cell damage due to a lack of oxygen and nutrients. The two primary causes of brain strokes are:  

    • Ischemic Stroke (About 87% of Strokes): This type occurs when a blood clot or other obstruction blocks the flow of blood to the brain. Common causes include:
      • Thrombosis: Formation of a clot within a blood vessel in the brain.  
      • Embolism: A clot or other debris that travels from another part of the body (often the heart) to the brain.  
      • Atherosclerosis: Buildup of fatty deposits in the arteries, narrowing them and leading to blockage.    
      • Risk Factors: High cholesterol, smoking, diabetes, and heart disease.     
    • Hemorrhagic Stroke: This type occurs when a blood vessel in the brain bursts, causing bleeding in or around the brain. It is usually caused by:  
      • High Blood Pressure (Hypertension): The most common cause, as it weakens blood vessels over time.  
      • Aneurysm: A bulge in a blood vessel that can rupture.  
      • Arteriovenous Malformation (AVM): A tangled network of blood vessels that can rupture.  
      • Trauma or Head Injury: Can cause bleeding in the brain.    
      • Risk Factors: Uncontrolled high blood pressure, head injuries, blood-thinning medications, and certain genetic conditions.   
    • Other Contributing Factors Lifestyle Choices: Poor diet, physical inactivity, obesity, and excessive alcohol or drug use.
      • Medical Conditions: Diabetes, heart rhythm disorders like atrial fibrillation, and family history of stroke.
      • Age and Gender: Risk increases with age, and men are generally at higher risk, though women can also be severely affected.

    1. next() Function: Reads the next token (word) from input. Delimiter: Stops reading when it encounters whitespace (space, tab, or newline). Ignores: Leading whitespace before the token. Use case: Good for reading single words. Example: Scanner sc = new Scanner(System.in); System.out.print("Enter yoRead more

    1. next()

    • Function: Reads the next token (word) from input.

    • Delimiter: Stops reading when it encounters whitespace (space, tab, or newline).

    • Ignores: Leading whitespace before the token.

    • Use case: Good for reading single words.

    Example:

    Scanner sc = new Scanner(System.in);
    System.out.print("Enter your name: ");
    String name = sc.next();
    System.out.println("You entered: " + name);

    Input:

    Rahul Sharma

    Output:

    You entered: Rahul

    👉 It only captures "Rahul" because next() stops at the first space.

    2. nextLine()

    • Function: Reads the entire line of input (until Enter/\n).

    • Delimiter: Stops only when the newline character is encountered.

    • Use case: Good for reading sentences or full lines with spaces.

    Example:

    Scanner sc = new Scanner(System.in);
    System.out.print("Enter your full name: ");
    String name = sc.nextLine();
    System.out.println("You entered: " + name);

    Input:

    Rahul Sharma

    Output:

    You entered: Rahul Sharma

    👉 Here it captures the whole line, including spaces.
