Load factor α in hash table can be defined … WebHashing is a type of a solution which can be used in almost all situations. Hashing is a technique which uses less key comparisons and searches the element in O (n) time in the worst case and in an average case it will be done in O (1) time. This method generally used the hash functions to map the keys into a table, which is called a hash table.
