Solution: Redundant Connection
Explore how to apply the union find algorithm to solve the redundant connection problem in an undirected graph. Learn to detect cycles by checking connectivity and understand the implementation details including path compression and union by rank to optimize performance.
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
