About This Simulator

See how hash tables work under the hood. Insert keys and watch them get hashed into buckets. When collisions occur, observe how different strategies (chaining vs open addressing with linear probing) resolve them. A great way to understand why hash tables offer O(1) average-case lookups and what happens when the load factor grows.

How It Works

  1. Type a key and click Insert to add it to the hash table
  2. Click Lookup to search for a key and see the hash computation
  3. Switch between Chaining and Linear Probing collision strategies
  4. Watch collisions highlighted in orange as they are resolved
  5. Observe the load factor to understand when performance degrades
  6. Click Clear to reset the table
