WebHash Function: A function that reduces a large phone number to a small practical integer value. In a hash table, the mapped integer value serves as an index. So, to put it simply, a hash function is used to convert a given key into a specific slot index. Its primary function is to map every possible key to a unique slot index. Web2.
