From Wikipedia,

In computing, a hash table, also known as a hash map, is a data structure that implements an associative array, also called a dictionary, which is an abstract data type that maps keys to values. A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value can be found. During lookup, the key is hashed and the resulting hash indicates where the corresponding value is stored.

In C programming -

• Hash tables use a hash function to map keys to indices in an array.
• They are used for efficient key-value pair storage and retrieval.

1. Write a C program that implements a basic hash table with functions for insertion, deletion, and retrieval of key-value pairs.

9. Write a C program that modifies a hash table to handle a generic data type, allowing it to store and retrieve data of any type.

10. Write a C program that creates a hash table to implement a simple spell checker. Load a dictionary of words into the hash table and check the spelling of input words.
