Word Search– LeetCode Problem
Problem:
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 constructed from letters of sequentially adjacent cells, where adjacent cells are horizontally or vertically neighboring. The same letter cell may not be used more than once.
Example 1:
![Word Search LeetCode Programming Solutions | LeetCode Problem Solutions in C++, Java, & Python [💯Correct] 2 word2](https://assets.leetcode.com/uploads/2020/11/04/word2.jpg)
Input: board = [["A","B","C","E"],["S","F","C","S"],["A","D","E","E"]], word = "ABCCED" Output: true
Example 2:
![Word Search LeetCode Programming Solutions | LeetCode Problem Solutions in C++, Java, & Python [💯Correct] 3 word 1](https://assets.leetcode.com/uploads/2020/11/04/word-1.jpg)
Input: board = [["A","B","C","E"],["S","F","C","S"],["A","D","E","E"]], word = "SEE" Output: true
Example 3:
![Word Search LeetCode Programming Solutions | LeetCode Problem Solutions in C++, Java, & Python [💯Correct] 4 word3](https://assets.leetcode.com/uploads/2020/10/15/word3.jpg)
Input: board = [["A","B","C","E"],["S","F","C","S"],["A","D","E","E"]], word = "ABCB" Output: false
Constraints:
m == board.length
n = board[i].length
1 <= m, n <= 6
1 <= word.length <= 15
board
andword
consists of only lowercase and uppercase English letters.
Word Search– LeetCode Solutions
Word Search in C++:
class Solution { public: bool exist(vector<vector<char>>& board, string word) { for (int i = 0; i < board.size(); ++i) for (int j = 0; j < board[0].size(); ++j) if (dfs(board, word, i, j, 0)) return true; return false; } private: bool dfs(vector<vector<char>>& board, const string& word, int i, int j, int s) { if (i < 0 || i == board.size() || j < 0 || j == board[0].size()) return false; if (board[i][j] != word[s] || board[i][j] == '*') return false; if (s == word.length() - 1) return true; const char cache = board[i][j]; board[i][j] = '*'; const bool isExist = dfs(board, word, i + 1, j, s + 1) || dfs(board, word, i - 1, j, s + 1) || dfs(board, word, i, j + 1, s + 1) || dfs(board, word, i, j - 1, s + 1); board[i][j] = cache; return isExist; } };
Word Search in Java:
class Solution { public boolean exist(char[][] board, String word) { for (int i = 0; i < board.length; ++i) for (int j = 0; j < board[0].length; ++j) if (dfs(board, word, i, j, 0)) return true; return false; } private boolean dfs(char[][] board, String word, int i, int j, int s) { if (i < 0 || i == board.length || j < 0 || j == board[0].length) return false; if (board[i][j] != word.charAt(s) || board[i][j] == '*') return false; if (s == word.length() - 1) return true; final char cache = board[i][j]; board[i][j] = '*'; final boolean isExist = dfs(board, word, i + 1, j, s + 1) || dfs(board, word, i - 1, j, s + 1) || dfs(board, word, i, j + 1, s + 1) || dfs(board, word, i, j - 1, s + 1); board[i][j] = cache; return isExist; } }
Word Search in Python:
class Solution: def exist(self, board: List[List[str]], word: str) -> bool: m = len(board) n = len(board[0]) def dfs(i: int, j: int, s: int) -> bool: if i < 0 or i == m or j < 0 or j == n: return False if board[i][j] != word[s] or board[i][j] == '*': return False if s == len(word) - 1: return True cache = board[i][j] board[i][j] = '*' isExist = \ dfs(i + 1, j, s + 1) or \ dfs(i - 1, j, s + 1) or \ dfs(i, j + 1, s + 1) or \ dfs(i, j - 1, s + 1) board[i][j] = cache return isExist return any(dfs(i, j, 0) for i in range(m) for j in range(n))
