Solution: Redundant Connection
Understand how to apply the union find pattern to detect redundant connections in undirected graphs. Explore step-by-step implementation details including union by rank and path compression to efficiently solve cycle detection problems in coding interviews.
Statement
We’re given an undirected graph consisting of nodes. The graph is represented as an array called edges, of length , 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 edges.
Constraints:
edges.length
