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 ... WebMar 20, 2024 · To implement DFS Traversal using an adjacency matrix in C, you can follow these steps: 1.
