Searching and Hashing
7. Discussion Questions
Using the hash table performance formulas given in the chapter, compute the average number of comparisons necessary when the table is
10% full
25% full
50% full
75% full
90% full
99% full
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.
