WebWe start off comparing hash tables with other data structures, and then going through how hash tables work, and ending with some mind-melting modular division. A hash function maps the universe of keys to array indices or slots within the table for each where and . The conventional implementations of hash functions are based on the integer universe assumption that all elements of the table stem from the universe , where the bit length of is confined within the word size of a computer architecture. A perfect hash function is defined as an injective function such that each element in maps to a uniq…
