This repository represents an intensive, comprehensive journey through Harvard University's CS50x: Introduction to Computer Science course. CS50x is one of the most prestigious and challenging introductory computer science courses globally, designed to teach students how to think algorithmically and solve problems efficiently.
CS50x is Harvard's introduction to computer science and the art of programming. It's designed for students with or without prior programming experience. The course teaches students how to think algorithmically and solve problems efficiently. Topics include:
- Abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development
- Languages include C, Python, SQL, JavaScript, CSS, and HTML
- Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming
