A good hash function should have the following characteristics:

Deterministic: For a given input, it should always produce the same output.
Uniform distribution: It should evenly distribute hash values across the hash table to minimize collisions.
Fast computation: It should be computationally efficient to compute the hash value.
Minimal collisions: It should minimize the likelihood of two different inputs producing the same hash value.
