Hashing Tutorial: Section 2.4 - Hash Functions for Strings

A good hash function should map the expected inputs as evenly as possible over its output range. That is, every hash value in the output range should be generated with roughly the same probability. The reason for this last requirement is that the cost of hashing-based methods goes up sharply as the number of collisions—pairs of inputs that are mapped to the same hash value—increases. If some hash values are more likely to occur than others, a larger fraction of th… WebApr 12, 2024 · When programming, we often need constant variables that are used within a single function.
