Everything about Open addressing

Hash collision resolution technique

Open addressing, or closed hashing, is a method of collision resolution in hash tables. With this method a hash collision is resolved by probing, or searching through alternative locations in the array until either the target record is found, or an unused array slot is found, which indicates that there is no such key in the table. Well-known probe sequences include:Linear probingin which the interval between probes is fixed — often set to 1. Quadratic probingin which the interval between probes increases linearly. Double hashingin which the interval between probes is fixed for each record but is computed by another hash function. Wikipedia →
