Solution: Redundant Connection

Explore how to apply the Union Find algorithm to detect and remove redundant edges in graphs. Understand the implementation details including union by rank and path compression, analyze time and space complexity, and solve the problem of making a graph a tree by eliminating cycles.

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:

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