Graph in gfg
WebDec 15, 2024 · A Bipartite Graph is a graph whose vertices can be divided into two independent sets, U and V such that every edge (u, v) either connects a vertex from U to V or a vertex from V to U. In other words, for every edge (u, v), either u belongs to U and v to V, or u belongs to V and v to U. WebFeb 2, 2024 · Depth First Traversal can be used to detect a cycle in a Graph. There is a cycle in a graph only if there is a back edge present in the graph. A back edge is an edge that is indirectly joining a node to …

WebFeb 7, 2024 · Complexity Analysis: Time Complexity: O(V+E) where V is number of vertices in the graph and E is number of edges in the graph. Space Complexity: O(V). There can be atmost V elements in the stack. So the space needed is O(V). Trade-offs between BFS and DFS: Breadth-First search can be useful to find the shortest path between nodes, and … WebFeb 14, 2024 · The idea is to represent a graph as an array of vectors such that every vector represents the adjacency list of a vertex.
