To solve the problem using DFS, we will use the DFS technique for exploring all the neighbours (maximum possible 8 of a number in the matrix) and check for 1’s. If we encounter 1 value which is unvisited, then we will consider it. We will keep a check on the values that are visited to avoid repeated visits.
