About Hash Table

Maps keys to buckets with a hash function for O(1) average lookup. Collisions are handled by chaining entries within a bucket.

Time complexity: O(1). Space complexity: O(n).

Use the interactive visualizer above to run Hash Table on your own input and watch every comparison, swap, and operation animate step by step — pause, scrub, or replay at any speed.
