Word search in grid

CodingAlgorithms & data structuresMid–Senior~25 min

Given a grid of characters and a word, return True if the word can be formed by a path of orthogonally adjacent cells, where each cell is used at most once per path. The grid has at most 5 rows and 5 columns. Return a boolean.

Implement
word_search(board: list[list[str]], word: str) → bool
Examples
in[[["A","B","C","E"],["S","F","C","S"],["A","D","E","E"]],"ABCCED"]outtrue
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
