Training Resources

Below are some resources for learning and practicing competitive programming.

Educational Resources

• UCSD Courses: CSE 109 (Introduction to Programming Contests) and CSE 190 (Introduction to Competitive Algorithmic Programming).
• Competitive Programming book: The newer editions are available for purchase and the 1st edition is available as a PDF here.
• cp-algorithms: A website that contains dozens of implementations of useful algorithms.
• Geeks for Geeks: This site provides lots of information on common algorithms.

Competition/Practice Sites

• Codeforces: This is one of the most famous competitive programming websites. You can participate in online competitions, solve problems from a huge problem bank, and learn from blogs and website solutions. A few of our favorites are 1 and2.
• VJudge: An online judge platform where you can participate in programming competitions by submitting problems to various other platforms. We also hold our weekly contests on VJudge
• Kattis hosts several official contests (you can find many regionals and world finals here).
• CodeChef Code-Chef is an online educational program and competitive programming community of global programmers.
