Alarm Clock

Sanggeun wakes up every morning with an alarm. However, after turning it off, he often sleeps a little longer and ends up late for school.

His friend Changyoung suggested setting the alarm 45 minutes earlier than the original time. This way, even if Sanggeun sleeps a little more after hearing the alarm, he can still wake up on time.

Given the currently set alarm time, determine what time the alarm should be changed to when this method is used.

The first line contains two integers H and M. They mean that the current alarm time is H hours and M minutes.

• 0 <= H <= 23
• 0 <= M <= 59

The time is given in 24-hour format. A day starts at 0:0 and the last minute of the day is 23:59. Unnecessary leading zeroes are not used when writing a time.

Print the alarm time after moving it 45 minutes earlier. Output H and M on one line, separated by a space, in the same format as the input.
