However, in a tree, each node (except the root node) comprises exactly one parent node. In graph theory, a matching in a graph is a set of edges that do not have a set of common vertices. Each job opening can only accept one applicant and a job applicant can be appointed for only one job. ... How to tackle problems based on Graph Theory? A tree is an undirected graph in which any two vertices are connected by only one path. Problem. A tree is an acyclic graph and has N - 1 edges where N is the number of vertices. Each test case contains 2 lines the first line contains two space separated integers v and e denoting the no of vertices and no of edges … Maximum matching in bipartite graphs is solvable also by maximum flow like below : Add two vertices S, T to the graph, every edge from X to Y (graph parts) has capacity 1, add an edge from S with capacity 1 to every vertex in X, add an edge from every vertex in Y with capacity 1 to T. Shortest Path ( BFS ) Docs. Maximum Matching in bipartite graphs. In other words, a matching is a graph where each node has either zero or one edge incident to it. Each applicant has a subset of jobs that he/she is interseted in. Then T test cases follow. Example 1: Input: c = 1, d = 2 Output: 1 Explanation: From the graph, we can clearly see that removing the edge 1-2 will result in disconnection of the graph. Code Monk II - Graph Theory . Given an undirected and connected graph of V vertices and E edges and another edge (c-d), the task is to find if the given edge is a bridge in graph, i.e., removing the edge disconnects the graph.
