Solution: Number of Islands
Explore how to apply the Union Find pattern to solve the Number of Islands problem on a 2D binary grid. Understand the process of initializing connections for land cells, performing union operations to merge adjacent lands, and counting distinct connected components to determine the total number of islands. This lesson helps you grasp efficient graph connectivity techniques useful in coding interviews.

Statement
Let’s consider a scenario with an 2D grid containing binary numbers, where '0' represents water and '1' represents land. If any '1' cells are connected to each other horizontally or vertically (not diagonally), they form an island. Your task is to return the total number of islands in the grid.
