If the matrix is 4-connected, we can use the same matrix. now we have to find the total number of connected components of a graph. consider 1 1 1 0 0 1 1 0 1 0 1 1 1 0 0 1 0 0 1 1 0 1 0 1 1 1 0 0 0 0 0 0 0 0 0 1 we can use bfs/dfs to mark the nodes as visited and thus total connected components can be counted.
