Learn more about Teams DJB2 is a simple hash function. It is called a polynomial rolling hash function. Bernstein (also known as djb ), this simple hash function dates back to 1991. To insert a key/value pair, the key is first hashed. value. So, this might be faring well in large data sets. The main advantages of this algorithm are a good distribution of the resulting hash codes, which results in a relatively low number of collisions, while at the same time being particularly fast to process, making it suitable for. This is c++ code of djb2 hash algorithm. Teams. - Prototype: unsigned long int key_index(const unsigned char *key, unsigned long int size); where key is the key - and size is the size of the array of the hash table - This function should use the hash_djb2 function that you wrote earlier - Returns the index at which the key/value pair should be stored in the array of the hash table - You will have to use this. int hash = string.
