Beginner Hint

\n\n- This challenge is in the Rev (Reverse Engineering) category.\n- Flag checkers are a common theme in Rev problems.\n- A flag checker executable or script accepts player input and tells you whether it matches the flag.\n- The provided files are the Ruby source `main.rb`.\n- The goal is to find an input (the flag) that makes the program print `Correct!`.\n\n

初心者向けヒント

\n\n- この問題は Rev カテゴリー、すなわち Reverse Engineering に関する問題です。\n- フラグチェッカーは、Rev の問題によくある題材の一つです。\n- フラグチェッカーと呼ばれる実行ファイルやスクリプトが、プレイヤーの入力を受け取り、その入力がフラグと一致するかどうかを出力します。\n- この問題の配布ファイルでは、Ruby のソースコード `main.rb` が与えられています。\n- 今回のゴールは、プログラムの出力が `Correct!` となるような入力（= フラグ）を探すことです。\n\n
