An ongoing quest to solve all Codeforces problems ordered by popularity and learn some modern C++ in the process.

All solutions are original and released into the Public Domain. Please see LICENSE for details.

Some caveats.

• The C++ version might be upgraded in the future following adoption by Codeforces.
• Some problems might be solved out of order as I (try to) compete in ongoing contests.
• Some problems are not actually solved: they do not pass all Codeforces tests. Such problems can be identified by a file named .unsolved in the problem directory.
