Gfg cycle in directed graph
WebCycle in Directed Graph - Problem Description Given an directed graph having A nodes. A matrix B of size M x 2 is given which represents the M edges such that there is a edge directed from node B[i][0] to node B[i][1]. Find whether the graph contains a cycle or not, return 1 if cycle is present else return 0.

WebMar 25, 2024 · How to detect a cycle in a Directed graph? In the following graph, It has a cycle 0-1-2-3-0 (1-2-3-4-1 is not cycle since edge direction is 1->4, not 4->1) Algorithm: Here we use a recursive method to detect a … WebDec 12, 2016 · The resulting graph is just a disjoint union of cycles. Take arbitrary node, run dfs, and find the length of the cycle it belongs to (just by visiting neighbour, a natural dfs). Continue this for every unvisited node. At the end you can output the largest cycle. Share Improve this answer Follow edited Dec 12, 2016 at 15:18

Add all nodes whose degree becomes equal to one to the queue. At the end of this algorithm, all the nodes that are unvisited are part of the cycle.
