CS50X is an online introductory course on computer science and programming. It teaches the languages C, Python, SQL, HTML, CSS & JavaScript, as well as fundamental computer science concepts such as algorithms & data structures, abstraction, encapsulation, resource management, security, and the Flask web framework.
An important part of the course, it's submitting the problem sets, as well as the final project for feedback. This repository contains the solutions I've come up with for the problem sets.
Also down below are links and short descriptions for each of the projects.
Keep in mind the course's academic honesty. You should try figuring out a solution yourself before looking at other implementations. Also, bear in mind that I am a beginner, I've taken the course to learn, so the solutions might not be the best implementations.

First of all, a huge thank you to Prof. David J. Malan and the rest of the CS50 staff for giving us this free learning opportunity. I thoroughly recommend the CS50 course for anyone who wants to get into or improve their skills in the Computer Science field.
