At what point do you think the hash table is too small? Explain.

Modify the hash function for strings to use positional weightings.

We used a hash function for strings that weighted the characters by position. Devise an alternative weighting scheme. What are the biases that exist with these functions?

Research perfect hash functions. Using a list of names (classmates, family members, etc.), generate the hash values using the perfect hash algorithm.
