C++14 -> C++20 (or higher)

There are no C++20 (nor even a lot of C++17) features in the current C++ compiler setup, which gets quite frustrating especially when trying to practice using newer standard containers, algorithms and patterns

Would it be possible to do a little update to allow usage of modern C++? Even just changing the compiler flags to a higher standard would be nice (your g++ 9.2.0 (I think) compiler does support c++17, but it seems to be disabled here for some reason), but upgrading to a newer compiler would be even nicer

I believe like this would encourage good, idiomatic programming habits as well, without much extra cost or work required

My current flow is literally coming here for the nice roadmap and UI, selecting my next problem, then finding its equivalent on Leetcode just so I can use C++20 😞
