I am maintaining an archive of C++ solutions for 2020 problems. Feel free to check out the link below if you have questions regarding a problem. Even if you are not using C++, reading through the comments may help you solve the problem in your preferred language. As time permits, I will be adding commented solutions of archived problems (2019 and before) from GCJ and Kickstart.
