Cycle in Undirected Graph | Problem Description Given an undirected graph having A nodes labelled from 1 to A with M edges given in a form of matrix B of size M x 2 where (B[i][0], B[i][1]) represents two nodes B[i][0] and B[i][1] connected by an edge. F
As we now have an overview of what a cycle is, Let us formulate an algorithm to detect a cycle in an undirected graph. For this, we will start from the source vertex and will traverse the graph using the breadth-first search algorithm. During traversal, if we find a vertex that has a...
detect cycle in an undirected graph with C++ implementation.Submitted bySouvik Saha, on March 19, 2019 What you will learn? How to detect a cycle in an undirected graph? In the graph below, It has cycles0-1-4-3-0or0-1-2-3-0 Algorithm Here we use arecursive method to detect a cyc...

Is this code to detect cycle in an undirected graph correct. I have run it on a few test cases and it seems good . Can someone from the community verify it. code:
To detect cycles in an undirected Graph using Depth First Search (DFS), we use a code very similar to the DFS traversal code on the previous page, with just a few changes.How it works: Start DFS traversal on each unvisited vertex (in case the Graph is not connected). During DFS, ...
Detect Cycle in a an Undirected Graph - To detect if there is any cycle in the undirected graph or not, we will use the DFS traversal for the given graph. For every visited vertex v, when we have found any adjacent vertex u, such that u is already visite
