...

• Makes a dir tree with code stubs.
• Downloads sample inputs and outputs.
• Allows local cpp includes, making a pretty single main.cpp.
• Tests the code against downloaded inputs and outputs.

• C++ code to edit is solve.cpp.
• C++ code to submit is main.cpp.
• Python code to edit and submit is main.py.
• Inputs are in$i, outputs are out$i with i in 0 1 2 ... . You can manually add new ones.

• Python 3.6+.
• Install extra libs with pip install -r requirements.txt.
• For C++ you need g++ with -std=c++2a and -fconcepts, version 9 is fine.
