WebIdeally, 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). In some cases, H (S1) can be equal to H (S2) which we call collision and can be minimized and taken care of as well WebJun 8, 2024 · The idea behind the string hashing is the following: we map each string into an integer and compare those instead of the strings.
