A search algorithm that uses hashing consists of two parts. The first part is computing a hash function which transforms the search key into an array index. The ideal case is such that no two search keys hashes to the same array index. However, this is not always the case and is impossible to guarantee for unseen given data. Hence the second part of the algorithm is collision resolution. The … WebA hash table contains several slots or buckets to hold key value pairs. It requires a hashing function to determine the correct bucket to place the data into. A hashing function is any algorithm, or formula, that is applied to a key to generate a unique number.
