A perfect hash function can, as any hash function, be used to implement hash tables, with the advantage that no collision resolution has to be implemented. In addition, if the keys are not the data and if it is known that queried keys will be valid, then the keys do not need to be stored in the lookup table, saving … See more In computer science, a perfect hash function h for a set S is a hash function that maps distinct elements in S to a set of m integers, with no collisions. In mathematical terms, it is an injective function. Perfect hash … See more A perfect hash function with values in a limited range can be used for efficient lookup operations, by placing keys from S (or other … See more A perfect hash function for a specific set S that can be evaluated in constant time, and with values in a small range, can be found by a See more Memory address identity A trivial but pervasive example of perfect hashing is implicit in the (virtual) memory address space of a computer.

This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map. Generally, these hash codes are used to generate an index, at which the value is stored. mouse pc ドライバ 更新
