Solution: Redundant Connection

Understand how to identify and remove redundant connections in an undirected graph by applying the union find pattern. Explore optimized cycle detection methods using union by rank and path compression to improve time complexity. This lesson helps you efficiently solve graph problems by recognizing redundant edges and constructing tree structures.

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:

$3 \leq$ $n$ $\leq 100$
edges.length $=$ $n$
edges[i].length $=$
