WebWe will take a look at the techniques to hash a string that is to convert a string to an integer. Ideally, an hashing technique has the following properties: If S is the object and H is the hash function, then hash of S is denoted by H (S). If there are two distinct objects S1 and S2, ideally, H (S1) should not be equal to H (S2).

WebRabin-Karp algorithm is an algorithm used for searching/matching patterns in the text using a hash function.
