WebNov 6, 2024 · My review for the question is to use clear structure, explicitly write down base case using comment and also put base case in the first line of depth first search function, and start from (0,0) to do depth first search and use recursive function to help iterate the matrix, avoid double for loop. The structure is more simple without double for loop.
