Decode the Coding Interview in Swift: Real-World Examples

DIY: Number of Connected Components in an Undirected Graph

Understand how to implement a function to count connected components in an undirected graph using Swift. Explore graph traversal and connectivity concepts to prepare for coding interviews focused on graph algorithms.

We'll cover the following...

Problem statement

Suppose you are given an undirected graph with n nodes. You are also given an integer n and an array edges where edges[i] = [xi, yi] indicates that there is an edge between xi and yi in the graph. Your task is to return the ...
