Solution: Redundant Connection

Explore how to identify and remove a redundant connection in an undirected graph using the Union Find algorithm. Understand the implementation of union by rank and path compression to efficiently detect cycles, optimizing graph connectivity checks.

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:

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