LeetCodeDepth-First SearchBreadth-First SearchUnion-FindGraph TheoryOpen on judge ↗

You are given an integer n. There is an undirected graph with n vertices, numbered from 0 to n - 1. You are given a 2D integer array edges where edges[i] = [ai, bi] denotes that there exists an undirected edge connecting vertices ai and bi. Return the number of complete connected components of the graph. A connected component is a subgraph of a graph in which there exists a path between any two
