CS Instructor Assessment

Task: in Python, implement a hash table with chaining collision resolution.

You can use a linked list or Python's built-in list type for collision chaining.

As a hashing function, implement either of:

  • DJB2
  • FNV-1 (64-bit)

(These can be googled and copied from pseudocode.)

Implement get, put, and delete functionality.

  • put(key, value) -- add a new key/value pair, or replace existing key's value
  • get(key) -- return the value for a given key
  • delete(key) -- remove a key/value pair

These operations should take ฮ˜(1) average time.

Implement tests using the built-in unittest module.

Bonus: resize the hash table when the load factor exceeds 0.7.

Email a ZIP of the archive back to your Lambda contact. git archive might be useful.
