You are provided with a 2-dimensional matrix having N
rows and M
columns, containing only 1s (land) and 0s (water). Your goal is to determine the number of islands in t...
Count the number of islands in a 2D matrix of 1s and 0s.
Iterate through the matrix and perform depth-first search (DFS) to find connected 1s.
Mark visited cells to avoid redundant calculations.
Increment island count whenever a new island is encountered.

Given an unsorted array of integers, move all zeroes to the end while maintaining the order of non-zero elements.
Iterate through the array and maintain two pointers, one for the current position and one for the position to swap with.
If the current element is non-zero, swap it with the element at the swap pointer and increment the swap pointer.
After iterating through the array, fill the remaining positions with zeroes.

representing asteroids aligned in a row, each element's absolute value identifies the asteroid's size, while its sign indicates the dir...
Determine the state of asteroids after collisions occur in a row.
Iterate through the array of asteroids and simulate collisions between adjacent asteroids moving in opposite directions.
If two asteroids collide, the larger one survives while the smaller one is destroyed.
Continue this process until no more collisions can occur.
Return the array of remaining asteroids after all collisions have been resolved.

Closures are functions that have access to variables from their outer scope even after the outer function has finished executing.
Closures are created when a function is defined within another function and has access to the outer function's variables.
They can access variables from the outer function even after the outer function has returned.
Closures are commonly used in event handlers and callbacks in JavaScript.
Event loop is a mechanism that allows JavaScript to perform non-blocking operations by handling asynchronous events.
Event loop is responsible for executing code, collecting and processing events, and executing queued sub-tasks.

Lifecycle of view refers to the stages a view goes through from creation to destruction in an application.
Creation: View is initialized and loaded into memory.
Layout: View is positioned and sized on the screen.
Display: View is rendered and displayed to the user.

Find the first duplicate value in an array of strings.
Create a hash table to store the frequency of each string.
Iterate through the array and check if the string already exists in the hash table.
If it does, return the string. If not, add it to the hash table.
If no duplicates are found, return null or an appropriate message.
