Coding Challenges - Core Tools and Systems Implementations

Overview

This collection of implementations consists of the solutions I implemented for the Coding Challenges designed by John Crickett. Each challenge focuses on building functional applications or utilities inspired by real-world tools and systems.

Through these challenges, my aim is to gain a deeper understanding of programming fundamentals, working of many tools, architectures and programming paradigms used in software development.

Projects

1. Unix wc Clone

A reimplementation of the Unix wc (word count) utility in Python that processes stdin text streams and files.

GitHub link to my implementation

Key Concepts:

• File I/O and stream processing
• Efficient parsing of large text inputs
• Command-line interface design

Highlights:

• Supports counting lines, words, and characters
• Handles multiple input sources (files and standard input)

2. Write your own Compression Tool

Implementation of file compression tool using the Huffman Coding Algorithm.

GitHub link to my implementation

Key Concepts:

• Built with Python
• File compression by reading and writing files in binary mode
• Command-line interface design

Highlights:

• Supports a wide variety of characters due to binary reading mode

3. Write your own cut Tool

Implementation of the Unix cut command using Python

GitHub link to my implementation

Key Concepts:

• Built with Python
• Handles two main options - -f to select fields to return and -d for the delimiter
• Command-line interface design

Highlights:

• Handles input by reading from file or through standard input stdin.
