To tylko hack, ale zbliży Cię
Tylko 3 posiłki
Zasadniczo klapki posiłki, jeśli zbliżą dwa dni do średniego C #
Lepszym rozwiązaniem byłoby zwrócenie boolen na Flopie i iterowanie aż do ukończenia.
Flop może stać się mądrzejszy. Możesz być w stanie nie flop śniadanie na flop lunch i kolację. Możliwe są permutacje kodu twardego. To bardziej przypomina sortowanie, w którym wartości flopa, a nie sortowanie.
