2024 had been an amazing year! We have literal child soldiers who represented Singapore in IOI, more K-POP and anime references thrown into December Course, a short martial law and two impeachments in South Korea, among many others.
Moreover, summarising2020 has been fixed!
You will now have to implement two files "xingyang.cpp" and "xyfriend.cpp"
xingyang.cpp should include xingyang.h and implement the function xythesnake.
xyfriend.cpp should include xyfriend.h and implement the function friendofxy.
