The time complexity of the above implementation of DFS on an adjacency matrix is O (V^2), where V is the number of vertices in the graph. This is because for each vertex, we need to iterate through all the other vertices to check if they are adjacent or not. The space complexity of this implementation is also O (V^2) because we are using an ... WebAn adjacency matrix is a way of representing a graph as a matrix of booleans (0's and 1's).
