Word Search

Explore the backtracking approach to solve the word search problem, which involves finding a given word by connecting sequentially adjacent cells in a character grid. This lesson will help you understand constraints, problem requirements, and implement an efficient solution using coding patterns relevant for technical interviews.

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.

Constraints:

  • m ==== board.length

  • n ...
