Hashmap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.
Hashmap uses an array to store key-value pairs.
Keys are hashed to determine the index where the value will be stored.
Collision handling is done by chaining or open addressing.
Retrieving a value involves hashing the key to find the index and then accessing the value at that index.
