Harden union-find connectivity
Hard Data Structures arena: path compression, union by rank, and component counts
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: data-structures-easy-graph-union-find
A network simulator tracks whether hosts are connected after cable repairs. You are working inside an interview-style data structure lab, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply path compression, union by rank, and component counts in an interview-style data structure lab while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates path compression, union by rank, and component counts
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.
