"WebApr 12, 2024 · I am trying to use DFS to solve the above problem. My approach is to. Traverse the grid using two indexes i and j. And wherever I encounter a 0 cell value, I start a DFS, as this is a Gate as per the problem definition. In the DFS algorithm, I first check the boundaries are satisfied or not. If out of boundary, then I return. " - Dfs python implementation
