Detailed explanation-1: -In a hash table, data is stored in an array format, where each data value has its own unique index value. Access of data becomes very fast if we know the index of the desired data. Thus, it becomes a data structure in which insertion and search operations are very fast irrespective of the size of the data.
Detailed explanation-2: -Furthermore, the average complexity to search, insert, and delete data in a hash table is O(1)-a constant time. It means that, on average, a single hash table lookup is sufficient to find the desired memory bucket regardless of the aimed operation.
Detailed explanation-3: -In computing, a hash table, also known as hash map, is a data structure that implements an associative array or dictionary. It is an abstract data type that maps keys to values.
Detailed explanation-4: -Hashing is simply passing some data through a formula that produces a result, called a hash. That hash is usually a string of characters and the hashes generated by a formula are always the same length, regardless of how much data you feed into it.
