Description

Given an m x n grid of characters board and a string word, return true if word exists in the grid.
The word can be constructed from letters of sequentially adjacent cells, where adjacent cells are horizontally or vertically neighboring. The same letter cell may not be used more than once.
Input: board = [["A","B","C","E"],["S","F","C","S"],["A","D","E","E"]], word = "ABCCED"
Output: true
My Approach - Using backtracking and DFS to solve the problem. As soon as we find the first letter of the word in any cell.
We will start moving forward recursively until we find the entire word, otherwise we will backtrack and traverse other possible paths.
