WebAug 29, 2024 · Detailed solution for Detect Cycle in an Undirected Graph (using DFS) - Problem Statement: Given an undirected graph with V vertices and E edges, check whether it contains any cycle or not. Examples: Example 1: Input: V = 8, E = 7 Output: No Explanation: No cycle in the given graph. Example 2: Input: V = 8, E = 6 Output: Yes … WebSep 26, 2024 · Here is an implementation for undirected graph. Note that in the undirected version, if a vertex v gets colored black, it will never be visited again by the DFS. This is because we already explored all connected edges of v when we first visited it. The connected component containing v (after removing the edge between v and its parent) …
