There are three different popular methods for open addressing techniques. These methods are −. Linear Probing. Quadratic Probing. Double Hashing. In this technique, we use a hash function like other hash techniques. WebThe types of Hashing Function in C are explained below: 1. Division method In this method, the hash function is dependent upon the remainder of a division. Example: elements to be placed in a hash table are 42,78,89,64 and let’s take table size as 10. Hash (key) = Elements % table size; 2 = 42 % 10; 8 = 78 % 10; 9 = 89 % 10; 4 = 64 % 10;
