Graph Traversal Problem

You are given an undirected graph and a particular starting node. Every node carries a distinct integer label. Your task is to return all the nodes you can reach from that starting node. Input: A collection of integer node IDs and a collection of undirected edges, where every edge is a two-element list [u, v]. An integer start — the node from which exploration begins. Output: A list of integers containing every node reachable from start, excluding the start node itself. The…
