In this technique, we store data or some keys in a fixed-size array structure known as a hash-table. Each key is mapped to a specific location on the hash-table. This mapping is known as a hash function.

WebExample 2: If Key=Address and Value=Student, and where Key is itself an Entity: Step 1: We define a way to get some integer value from this Key. e.g. for Address, the pin code makes sense. Step 2: Hashing takes Pin code as the Input, and will return the Memory Location to place this Key-Value pair at. WebHashing in Data Structure Searching is dominant operation on any data structure.
