Solution: Word Search
Explore the backtracking method to solve the Word Search problem on a grid. Understand how to apply depth-first search to traverse cells, check boundary conditions, and backtrack to explore all paths. Learn to implement a recursive solution that efficiently finds if a given word can be formed by sequential letter adjacency without revisiting cells.
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.
