Ini hanya retasan tetapi akan membuat Anda tutup
Hanya 3 kali makan
Pada dasarnya Anda gagal makan jika itu membuat dua hari lebih dekat dengan rata-rata C #
Pendekatan yang lebih baik adalah mengembalikan boolen pada Flop dan beralih kembali sampai selesai.
Flop bisa menjadi lebih pintar. Anda mungkin berada dalam posisi tidak gagal sarapan untuk gagal makan siang dan makan malam. Mungkin ada permutasi kode yang sulit. Ini lebih seperti semacam nilai gagal daripada menyortir.
