A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used to index a hash table holding the data or records, or pointers to them. A hash function may be considered to perform three functions: WebAug 21, 2024 · Define a hash function f (x) = x mod 1000000. And now the x in S will be converted into [0,1000000), OK, But you will find that many numbers in S will convert into one number. for example. the number k * 1000000 + y will all be located in y which because (k * 1000000 + y ) % x = y.
