Hashmap is a data structure that stores key-value pairs and uses hashing to locate values based on their keys.
Hashmap uses an array to store the key-value pairs
The key is hashed to generate an index in the array
If two keys hash to the same index, a collision occurs and the values are stored in a linked list
Hashmap provides constant time complexity for insertion, deletion, and retrieval of values
