One such hash function is DJB2, which stands for Daniel J. // For when you ever need to implement a dictionary hash function, // that's good enough, simple and fast. FileName: StringGetBytesExample. DJB2 is similar to a Linear congruential generator and uses prime numbers 5381 and 33 to generate a psuedo-random unsigned quad given a sequence of signed bytes. In this article. Then the nodes (items in the table) contain keys and values. This resulted in the following code: unsigned int hash (const char *str) { unsigned int hash = 5381; int c; while (c = *str++) hash = ( (hash << 5) + hash) + c; /* hash * 33 + c */ return hash; } At this point, the compiler told me that I had to put parenthesis. unsigned long int Hash_Table::hash. runelite.
