Q1. Calculate Number of Islands
Ans. 
Count the number of connected islands in a 2D grid of '1's and '0's.
• Iterate through the grid and for each '1' encountered, perform a depth-first search to mark all connected '1's as visited.

• Increment the island count for each new island found.

• Optimize by using a visited array to keep track of visited cells to avoid revisiting them.
