Is problem 94 good?

Due: April 29
Points: 2

Problem 94 asks you to build a perfect static hash table that stores all prime numbers less than 1 million. This can be used to quickly test whether any integer less than 1 million is prime.

Compare this method of primality testing to the following two other ideas that would accomplish the same thing:

  • Store all these prime numbers in a Bloom filter instead of a perfect hash table.
  • Use the Miller-Rabin algorithm

When I say "compare", I mean give the relative strengths and weaknesses of each approach. The things you might consider are time, memory, and the probability of getting the right answer.
