WebAug 10, 2024 · Detailed solution for Number of Provinces - Problem Statement: Given an undirected graph with V vertices. We say two vertices u and v belong to a single province if there is a path from u to v or v to u. Your task is to find the number of provinces. Pre-req: Connected Components, Graph traversal techniques Examples: Input: Output: 3 … WebAlgorithm of DFS in C. Step 1: One of the standard rule before starting with DFS algorithm is that DFS puts each vertex of graph into two categories i.e. Visited & Non Visited. Step 2: Keeping in mind that each vertex is visited at least once without making cycles. Step 3: First, need to put any one graph vertices on top of the stack.

WebUndirected Graphs. We define an undirected graph API and consider the adjacency-matrix and adjacency-lists representations. We introduce two classic algorithms for searching a graph—depth-first search and breadth-first search. We also consider the problem of computing connected components and conclude with related problems and applications. WebApr 20, 2024 · A Computer Science portal for geeks.

Basically, there are two algorithms used for topological sort, described on Wikipedia. Kahn's algorithm works with any graph traversal, including BFS or DFS. Tarjan's algorithm, which is now the most well known, uses a "reverse DFS postorder" traversal of the graph. Postorder means you add a node to the list after visiting its children. bruins all time scoring list
