Changes: Change DP state to 4D. Remove variable hashNum in function dfs. Description: The value of grid[i][j] does not need to be included as a DP state variable because it does not change during iteration. This reduction in dimensionality improves space complexity. The existing solution exceeds the time limit on some test cases.
