C Program: Hash Table Implementation and Operations
This resource offers a total of 50 C Program to implement Hash Tables problems for practice. It includes 10 main exercises, each accompanied by solutions, detailed explanations, and four related problems.
[An Editor is available at the bottom of the page to write and execute the scripts.]
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. Basic Hash Table Extended Challenges
Write a C program that implements a basic hash table with functions for insertion, deletion, and retrieval of key-value pairs.
2. Collision Resolution Extension Challenges
Implement a basic hash table in C with functions for insertion, deletion, and retrieval of key-value pairs. Write a C program that extends the above basic hash table implementation to handle collisions using techniques such as chaining or open addressing.
3. String Hash Function Challenges
Write a C program that creates a hash function specifically designed for strings and implements a hash table to store and retrieve string data.
4. Dynamic Resizing Challenges
Write a C program that implements dynamic resizing in a hash table to automatically adjust its size when the load factor exceeds a certain threshold.
5. Extended Hash Table Operations Challenges
Write a C program that performs various operations on a hash table, including inserting, deleting, and searching for elements.
6. Hash Table Statistics Challenges
Write a C program that calculates and displays statistics about the hash table, such as load factor, average chain length, and distribution.
7. Open Addressing Techniques Challenges
Write a C program that implements a hash table using open addressing techniques like linear probing or quadratic probing to resolve collisions.
8. Collision Resolution Performance Comparison Challenges
Write a C program that compares the performance of different collision resolution methods (chaining, linear probing, etc.) in terms of speed and memory usage.
9. Generic Hash Table Challenges
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. Hash Table Spell Checker Challenges
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.
