WebJul 8, 2024 · The purpose of hashing is to achieve search, insert and delete an element in complexity O (1). Hash function is designed to distribute keys uniformly over the hash table. Load factor α in hash table can be defined as number of slots in hash table to number of keys to be inserted. For open addressing, load factor α is always less than one.
