Yes. Wrap-around adjacency is a fundamental K‑map rule, and if a quad only appears when wrapping is used, that quad must be taken as part of the minimal grouping and included in the final simplified expression.
K‑map grouping rules
Wrapping allowed: In a K‑map, the left and right edges, and the top and bottom edges, are adjacent; groups may and should wrap around these edges to form larger valid groups.
Largest possible groups: To obtain a minimal expression, always form the largest groups (octets, then quads, then pairs), even if this requires overlapping or wrap‑around groups.
Overlap vs redundancy: Overlapping groups are allowed and often reduce the expression, but a group is redundant only if all its 1s are already covered by other groups and removing it does not leave any 1 uncovered.
Applying this to your situation
See lessIf, after allowing wrap‑around, a quad covers some 1s that would otherwise only be in smaller groups, then that quad is not redundant and should be used; it will generally yield a simpler term.
If a quad becomes completely overlapped by other groups so that every 1 in it is already covered, then it is redundant and should be removed from the final expression; otherwise, include it.

Operation Sagar Bandhu (translated as “Friend of the Seas”) is a major humanitarian mission launched by India on November 28, 2025, to assist Sri Lanka in the aftermath of the devastating Cyclone Ditwah. The operation is a prime example of India’s “Neighbourhood First” policy and its Vision MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions), positioning India as the primary “first responder” for natural disasters in the Indian Ocean.
Key Objectives and Impact
Humanitarian Aid: India has delivered over 1,134 tonnes of essential supplies, including dry rations, fresh food, medicines, surgical equipment, tents, and water purification units.
Search and Rescue (SAR): Indian helicopters (Chetak and MI-17) have rescued hundreds of stranded individuals, including pregnant women, infants, and foreign nationals from over a dozen countries.
Infrastructure Restoration: An Engineer Task Force from the Indian Army was deployed with Bailey bridges and heavy machinery to restore critical road connectivity in flood-hit regions like Kilinochchi.
Medical Assistance: The Indian Army’s 60 Parachute Field Hospital treated more than 7,000 patients, providing surgical, dental, and general medical care in severely affected areas.
Military Assets Involved
The mission saw a massive, coordinated effort between the Indian Navy, Air Force, and Army:
See lessIndian Navy: Deployed the aircraft carrier INS Vikrant, the frigate INS Udaygiri, and several other ships including INS Sukanya and INS Gharial.
Indian Air Force: Utilized C-130J Super Hercules and C-17 Globemaster transport aircraft for rapid airlifting of personnel and heavy equipment.
Indian Coast Guard: The ship ICGS Shaurya delivered significant consignments of dry rations.
NDRF: Specialized teams from the National Disaster Response Force assisted in ground-level search and recovery operations.
In Java programming sum(5,6) will call for which of these …
In Java, the method that will be called when you write sum(5, 6) depends on method overloading resolution, which considers the most specific match based on the types of the arguments.

In Java, the method that will be called when you write sum(5, 6) depends on method overloading resolution, which considers the most specific match based on the types of the arguments.
Given:
sum(5, 6);
Here, both arguments are integers (int literals).
And you have two overloaded methods:
sum(int a, int b)
sum(double a, int b)
Resolution:
Java will choose the most specific method that matches the argument types without needing conversion.
sum(int a, int b) matches exactly.
sum(double a, int b) would require widening the first int to a double.
Therefore, sum(int a, int b) will be called.
Summary:
In Java, when overloading methods:
Java prefers exact matches.
Widening conversions (like int to double) are only used if no exact match is found.
So:
sum(5, 6); // calls sum(int a, int b)

The best nature-based solutions (NbS) for restoring wetlands and preventing floods work by mimicking or enhancing natural processes to improve water management, biodiversity, and resilience to climate impacts. Here are the most effective strategies:
🌿 1. Wetland Restoration and Reconnection
What it is: Rehabilitating degraded wetlands by reintroducing native vegetation, removing invasive species, and reconnecting wetlands to rivers and floodplains.
Benefits: Restores the wetland’s natural ability to absorb and slow floodwaters, filter pollutants, and support wildlife.
🌊 2. Floodplain Reconnection
What it is: Allowing rivers to overflow into their natural floodplains by removing levees or modifying embankments.
Benefits: Reduces flood peaks downstream, replenishes groundwater, and improves habitat quality.
🌱 3. Reforestation and Riparian Buffer Zones
What it is: Planting native trees and vegetation along rivers and streams.
Benefits: Stabilizes soil, reduces erosion, slows runoff, and enhances water infiltration, reducing the severity of floods.
🐟 4. Restoring Natural Hydrology
What it is: Removing drainage systems, dams, or other artificial barriers that alter water flow.
Benefits: Restores natural water cycles, increases water retention in landscapes, and supports wetland function.
🌾 5. Constructed Wetlands and Retention Basins
What it is: Creating man-made wetlands designed to mimic natural ones for water storage and filtration.
Benefits: Helps manage stormwater, reduces urban flooding, and treats runoff before it enters natural water bodies.
🌬️ 6. Coastal Wetland and Mangrove Restoration (for coastal areas)
What it is: Replanting and protecting salt marshes or mangroves.
Benefits: Acts as a buffer against storm surges, reduces coastal flooding, and supports marine biodiversity.
✅ Summary of Benefits:
Flood regulation through water storage and slowed runoff
Water purification by filtering sediments and pollutants
Carbon sequestration and climate resilience

Taenia solium is the pork tapeworm, a parasitic flatworm (helminth) that infects both humans and pigs.
- Taeniasis – infection with the adult worm, usually mild, from eating undercooked pork containing larval cysts.
- Cysticercosis – infection with larval cysts in tissues after ingesting eggs, which can lead to neurocysticercosis when the brain is affected, causing seizures and other neurological problems.
See lessType of organism: Parasitic cestode (tapeworm)
Hosts:
Definitive host: Humans (adult worm lives in the small intestine)
Intermediate host: Pigs (larval cysts in muscles) — but humans can also become accidental intermediate hosts.
Diseases caused:
Transmission:
Eating undercooked or raw pork containing cysticerci (larvae).
Consuming food or water contaminated with tapeworm eggs from human feces.
Significance: Recognized by the WHO as a major cause of preventable epilepsy worldwide, especially in parts of Latin America, Africa, and Asia.

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.

Primary amebic meningoencephalitis (PAM) is a rare, usually fatal brain infection caused by the amoeba Naegleria fowleri. This free-living amoeba is commonly found in warm freshwater environments like lakes, rivers, and hot springs, as well as in poorly maintained pools or contaminated water supplies.
PAM occurs when the amoeba enters the body through the nose, typically during activities like swimming or diving. From there, it travels to the brain, causing severe inflammation of the brain and its surrounding membranes (meningoencephalitis). Symptoms usually start within 1–9 days and include headache, fever, nausea, vomiting, stiff neck, confusion, seizures, and coma. The infection progresses rapidly, often leading to death within days if untreated.
Diagnosis is challenging and typically involves detecting the amoeba in cerebrospinal fluid or brain tissue, often confirmed posthumously. Treatment is difficult due to the rapid progression and limited effective drugs, but regimens may include antifungal and antimicrobial agents like amphotericin B, miltefosine, and others, with supportive care. Survival is rare, with only a few documented cases globally.
Prevention focuses on avoiding exposure: using nose clips while swimming in warm freshwater, ensuring proper pool maintenance, and avoiding untreated water for nasal irrigation. The CDC and WHO emphasize that PAM is not contagious and cannot be contracted from drinking contaminated water.
