Solution: Word Search
Explore how to solve the word search problem using backtracking and depth-first search. Learn to traverse a 2D grid by checking adjacent cells and using recursion to find a target word while managing visited cells. Understand the approach to efficiently backtrack when paths fail and handle grid boundaries, gaining skills to apply this strategy in coding interviews.
We'll cover the following...
Statement
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 formed by connecting letters of sequentially adjacent cells. The cells are considered sequentially adjacent when neighbors are either horizontally or vertically neighbors. Each cell can be used only once while forming the word.
