Number of islands | Leetcode #200

This video lecture explains a very important interview programming question which is to find number of islands on a matrix or grid. This is same as finding the number of clusters on a graph or matrix or grid. This is a typical DFS or BFS problem under graph algorithms. This can also be solved using Disjoint Set. I have explained the DFS approach for this problem using examples and code explanation. As usual, CODE LINK is given below. If you find any difficulty or have any query then do COMMENT below.
