In thearray loops sectionin the previous chapter, we wrote the size of the array in the loop condition (i < 4). This is not ideal, since it will only work for arrays of a specified size. However, by using thesizeofformula from the example above, we can now make loops that work fo...

F B C A E D G Is cyclic: DFS Cycle Detection To implement DFS cycle detection on a directed Graph, like in the animation above, we need to remove the symmetry we have in the adjacency matrix for undirected Graphs. We also need to use a recStack array to keep track of visited ...
The parent array holds the parent of a vertex, creating a path from the sink vertex, backwards to the source vertex. The parent is used later in the Edmonds-Karp algorithm, outside the bfs method, to increase flow in the augmented path....
