This is a 100+ part playbook that takes you from basic C++ programming to a Gold medal at IOI. It has tutorials on 30+ algorithms and data structures, and 75+ problems based on those topics, sorted by increasing difficulty.

This playlist covers the required amount of C++ / Java / Python knowledge you need for programming contests such as Olympiad in Informatics, CodeChef, Codeforces, etc.

Since the last few days, the IARCS website has been down and giving fatal error for C++ submissions. For the time being, I request people to skip the IARCS problems. I've contacted the maintainers, and they said they'll fix it soon. You can still continue making submissions for non-C++ languages.

If you know alternate websites with similar problems, you can help by posting a link to the problem as a reply to the discussion. Tag it with alternate websites, so that it is easy to find.

You can follow this discussion by clicking the thumbs up button. I'll post a reply when they fix it and you'll get a notification.
