Hashing: Hashing is a technique to store data within an array so which storing, searching, inserting and deleting data is fast (in theory it's O(1)). For this every record requires an unique key.
The primary idea is not to find for the correct position of a record along with comparisons but to compute the position inside the array. The function which returns the position is known the 'hash function' and the array is called a 'hash table'.
