This repository is dedicated to storing my projects, notes and files related to Harvard University's CS50x course.
I started this course on April 11, 2024.
- Lecture Notes: I keep detailed notes of lectures and supplementary materials.
- Problem Set Solutions: Explore my solutions to the problem sets and additional practices assigned in CS50x, including programs written in C, Python, and other languages.
- Work in Progress: This repository is a work in progress and will be continually updated as I progress through the course.
CS50x is an introductory course to computer science offered by Harvard University. It covers a wide range of topics, including programming in C, Python, web development, and more. The course is designed to be challenging yet accessible to beginners, making it an excellent choice for those looking to dive into the world of computer science.
