Cycles in a graph

Revision en5, by tgp07, 2022-05-20 05:49:38

Let's you have a graph with n nodes and m bi-directional edges. (n, m <= 1e5). How would I get the cycles in this graph in an efficient way using DFS.

BTW, I've linked an image where I drew what I thought is a cycle. If it's not a cycle, please tell me what a cycle actually is.
