開発堕ち

まあ AI に聞いただけなんだけど

https://archive.topcoder.com/ProblemArchive

SRM フォルダを作って、中に solution.cpp (解法,これは本番通りにclassで書く) と tests.txt (各問題を開いて全てをコピペしたら良い) と judge.py (中身は後述) を置く

python3 judge.py をしたら、

=== testproblem | 3 Cases ===

Case 00: [ TLE ] (3.0s exceeded)
Case 01: [ TLE ] (3.0s exceeded)
Case 02: [ OK ] (0.0000s)

===================================
 最終結果まとめ
===================================
 OK: 1 | NG: 0 | TLE: 2 | RE: 0
 Max Time: 3.0000s
===================================

みたいなのが出てくる

バグってるかは知りません、スペシャルジャッジは見なかったことにしよう
本当に問題文コピペだけでいけるのは偉いと思った、room移動で10分待ちなんてなかったんや

おまけ
