Solution: Redundant Connection

Explore the Union Find pattern to solve the redundant connection problem in undirected graphs. Understand how to detect cycles efficiently by connecting nodes and returning the edge that creates a cycle. This lesson guides you through building the solution incrementally for optimal time and space complexity.

Statement

We’re given an undirected graph consisting of $n$ nodes. The graph is represented as an array called edges, of length $n$ , where edges[i] = [a, b] indicates that there is an edge between nodes a and b in the graph.

Return an edge that can be removed to make the graph a treeA tree is an undirected graph that is connected and has no cycles. of $n$ nodes. If there are multiple candidates for removal, return the edge that occurs last in edges.

Constraints:

$3 \leq$ $n$ $\leq 100$
