Detailed explanation-1: -March 01, 2022. Division Modulo Method is the simplest method of hashing. In this method, we divide the element with the size of the hash table and use the remainder as the index of the element in the hash table.
Detailed explanation-2: -With modular hashing, the hash function is simply h(k) = k mod m for some m (usually, the number of buckets). The value k is an integer hash code generated from the key. If m is a power of two (i.e., m=2p), then h(k) is just the p lowest-order bits of k.
Detailed explanation-3: -Hash functions are mathematical functions that transform or “map” a given set of data into a bit string of fixed size, also known as the “hash value.” Hash functions are used in cryptography and have variable levels of complexity and difficulty.
Detailed explanation-4: -For hashing, prime numbers are used since they provide a better chance of creating unique values for a hash function.
