Solution: Redundant Connection

Explore how to solve the Redundant Connection problem by applying the Union Find pattern. Learn to identify and remove redundant edges that create cycles in an undirected graph, ensuring the graph forms a tree. Understand step-by-step implementation improvements including union by rank and path compression techniques to optimize cycle detection and connection of graph nodes efficiently.

Statement

We’re given an undirected graph consisting of $n$ nodes. The graph is represented as list 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.
