WebApr 13, 2016 · Viewed 2k times. 3. Below is my code to detect cycle in an undirected graph. Could anyone please review and let me know if I have taken care of all the cases? The basic idea is to use DFS (non-recursive using stack) and check if already visited vertices are found in the stack. bool dfsDetectCycle (int vertex, int visited [10]) { … WebDec 28, 2024 · Union-Find Algorithm can be used to check whether an undirected graph contains cycle or not. Note that we have discussed an algorithm to detect cycle. This is another method based on Union-Find. This method assumes that the graph doesn\’t contain any self-loops. We can keep track of the subsets in a 1D array, let\’s call it parent[].

WebFigure 7 shows DFS applied to an undirected graph, with the edges labeled in the order they were explored. Below we list the vertices of the graph ordered by discover and finish time, as well as show the parenthesis structure. ...
