Hash in cpp gfg
WebHere, we will look into different methods to find a good hash function. 1. Division Method. If k is a key and m is the size of the hash table, the hash function h() is calculated as: h(k) = k mod m. For example, If the size of a hash table is 10 and k = 112 then h(k) = 112 mod 10 = 2. The value of m must not be the powers of 2. WebFeb 10, 2024 · What is the hash map in c++? Hash map is nothing but the unordered map. Hash map stores the data in the unordered form.
