WebJul 29, 2024 · The only thing that's required for a valid hash function is that it produces a number for all inputs and X==Y => h(X)==h(Y). Your code should behave correctly (albeit slowly) even if it's all collisions (e.g. h(X)=0). As a step two, a good hash function should minimize collisions.
