The Java engineers like to use a simple polynomial hash function: for (int i = 0; i < len; i++) { h = 31 * h + val[i]; } That function is very fast. Unfortunately, as it is written, it is not optimally fast for long arrays. The problem comes from the multiplication. cvtケーブルとは 3相3線WebApr 28, 2015 · Ideally, hashsets approach a constant lookup time (specifically it's O(log 2^H N) where H is the bitsize of the hash function, so for all N < 2^H it's effectively constant), so overall, your matching algorithm would approach linear complexity.
