Witryna29 sie 2016 · Integers For the integers tests, we use hash maps with int64_t as key and int64_t as value. The std::hash of Clang with libstdc++ used by the benchmark is an identity function (the hash of the ‘42’ integer will return ‘42’). Random shuffle inserts: execution time (integers) Witryna21 mar 2024 · The integer hash function transforms an integer hash key into an integer hash result. For a hash function, the distribution should be uniform. This implies when the hash result is used to calculate hash bucket address, all buckets are equally likely to be picked. In addition, similar hash keys should be hashed to very different hash results. chislehurst life magazine
