-Задача ЕЛЕКТРОНЕН ЧАСОВНИК
-В големия нов МОЛ в града на програмистите се повредили част от цифрите на електронния часовник.
-Повредени били първата цифра от числото, което показва часовете, втората цифра на числото, което показва минутите и първата цифра на числото, което показва секундите.
-Вместо тях на екрана се появявал знака *.
-Когато Коко и приятелите му ходели на кино, те не успявали да преценят точно колко е часа.
-Все пак, момчетата си създали система за изчисление, която приблизително точно им показвало времето.
-Те успявали да предвидят колко е показвал часовника в началото и края на филма, в случай че знаят точно колко време е минало.
-Срещу името на всеки филм на входа на киното е дадено неговото времетраене в часове, минути и секунди.
-Пресмятанията доста затрудняват момчетата и затова на тях ще им е по-удобно това да се прави с компютърна програма.
-Те не разбират много от програмиране и затова вие трябва да напишете програма clock, която помага на Коко и приятелите му.
-
-Вход:
-На първия ред на стандартния вход е записана последователност от цифри и знака *, която показва какво се вижда на екрана на часовника в началото на филма.
-На втория ред е записана подобна последователност за показанието на часовника в края на филма.
-На третия ред се въвежда продължителността на филма в часове, минути и секунди.
-Часовникът е настроен така, че показва времето по 12-часова скала, а не по 24-часова.
-
-Изход:
-На стандартния изход изведете всички възможни показания на часовника за началото и края на филма.
-Всяка двойка с начален и краен час се извежда на един ред, като първо се извежда началното показание във формат hh:mm:ss, и след един интервал крайното показание в същия формат.
-Ако такива показания на часовника не са възможни, да се изведе “Impossible”.
-
-Ограничения:
-Продължителността на филма е не по-голяма 12 часа.
-
-Примери:
-
-Вход:
-*25**6
-*10**2
-10 19 26
-Изход:
-02:50:06 01:09:32
-02:50:16 01:09:42
-02:50:26 01:09:52
