Solution: Word Search
Explore how to solve the Word Search problem using backtracking and depth-first search techniques. This lesson guides you through checking base cases, validating grid cells, and recursively searching adjacent cells to find a given word. You will understand how to manage visited cells and backtrack when paths do not lead to a solution, optimizing time and space complexities in a constrained grid.
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.
