Number of Islands solution | Leetcode Graph DFS HIndi | Graph Hello world Playlist #200

This is the video under the series of DATA STRUCTURE & ALGORITHM in a GRAPH Playlist. Now we are going to solve the Number of Islands Depth First Search ( DFS ).
In this video, we are going to solve the "Number of Islands" which is a basic Question on the GRAPH series.

---------------------------------------------------------------------------------------

► 200. Number of Islands
Given an m x n 2D binary grid which represents a map of '1's (land) and '0's (water), return the number of islands.
An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. You may assume all four edges of the grid are all surrounded by water.

Input: grid = [
["1","1","0","0","0"],
["1","1","0","0","0"],
["0","0","1","0","0"],
["0","0","0","1","1"]
]
Output: 3

We also Provide courses on Competitive Programming and Data structure and Algorithms. Please see our Full Playlist on our Channel.
