Double hashing is a collision resolution technique used in open-addressed hash tables. It uses a second hash function to determine the next probing location, applying a different hashing function for each probe attempt. When inserting a key into the hash table, a second hash function is used to determine the step size for probing. The formula for double hashing is New index = (Hash index + step size) mod Table size, where step size is the number of times probed. The key is then placed in the first available empty slot. When deleting a key, the hash index is calculated, and the slot is marked as deleted or removed.
