WebApr 16, 2024 · Division method of hashing. Does anybody know why if hashed data with with m = 2, I should write h (k) = k mod 2^p (where p is lowest-order bits of k), but if hashed data with m > 2 (5,20,44) to write h (k) = k mod 5? I know that we should avoid m = 2. And what is it "power of 2", "m shouldn't be power of 2"? k - key m - size of hash table p ...

In the above formulas, k(mod m) indicates the remainder when k is divided by m. The first formulae range hash addresses from 0 to m-1 where second …

Web"When using the division method, we usually avoid certain values of m (table size). For example, m should not be a power of 2, since if m = 2^p , then h(k) is just the p lowest-order bits of k. Unless it is known that all low-order p bit patterns are equally likely, it is better to make the hash function depend on all the bits of the key."--CLRS WebThe hash function takes any item in the collection and returns an integer in the range of slot names between 0 to n-1. Suppose we have integer items {26, 70, 18, 31, 54, 93}.
