Graph Theory and Union-Find Data Structure Applications in Island Problems
Maximum Island Area Problem
Given a matrix of 1's (land) and 0's (water), calculate the maximum island area. Islands consist of adjacent land cells connected horizontally or vertically.
Input:
4 5
1 1 0 0 0
1 1 0 0 0
0 0 1 0 0
0 0 0 1 1
Output: 4
The solution uses DFS or BFS to traverse each island component and count its area.
