Hashing Questions
Double hashing in open addressing is a collision resolution technique used in hash tables. It involves using a second hash function to determine the next available slot in the hash table when a collision occurs. The second hash function is applied to the original hash value, and the resulting value is used to calculate the next slot to probe. This process continues until an empty slot is found or the entire hash table is traversed. Double hashing helps to distribute the keys more evenly and reduces the chances of collisions, improving the efficiency of the hash table.
