Graph Valid Tree

You are provided with n nodes labeled 0 through n - 1, together with a list of undirected edges where each entry edges[i] = [a, b] joins node a to node b. Determine whether these edges constitute a single, valid tree — meaning the entire graph is fully connected and contains no cycles. Return true if it does; return false otherwise. Examples Example 1 Explanation: Node 1 links to the other three nodes, and there is no cycle. Example 2 Explanation: Nodes 0, 1, and 2 create a…
