Hash map is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hash map consists of an array of buckets, each containing a linked list of key-value pairs.
When inserting a key-value pair, the hash function is used to determine the index of the bucket where the pair should be stored.
To retrieve a value, the hash function is used to find the corresponding bucket...
