Solution: Redundant Connection
Explore how to detect and remove a redundant connection in an undirected graph by applying the union find data structure with path compression and union by rank. Understand the step-by-step construction of an efficient cycle detection method to optimize for time and space complexity.
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
