# Competitive Programming 4 Solutions
My solutions to some of the [Kattis](https://open.kattis.com/) problems listed in [Competitive Programming 4](https://cpbook.net/details?cp=4).
Some [UVA Online Judge](https://onlinejudge.org/) problems are also solved on [Virtual Judge](https://vjudge.net/).

C++ code usually requires C++17 to work.
Python code usually requires Python 3.8 to work.
