529. Minesweeper

Leetcode Solutions

Depth-First Search (DFS) Approach

  1. Check if the clicked square is a mine ('M'). If so, mark it as 'X' and return the board.
  2. If the clicked square is an empty square ('E'), perform a DFS starting from this square.
  3. In the DFS function, first count the number of adjacent mines.
  4. If there are adjacent mines, mark the square with the count and return.
  5. If there are no adjacent mines, mark the square as 'B' and recursively call DFS on all adjacent squares that are still unrevealed ('E').
  6. Continue the process until all squares that need to be revealed are processed.
  7. Return the updated board.
