O-angle meter
Little Gondra received a digital angle meter as a gift. While measuring an angle the display shows numbers representing: degrees, minutes and seconds of the measured angle. Gondra enjoys measuring angles whole day, and he wants to know what is first integer fraction of the measured angle he can not measure with his new digital angle meter.
(0 <= D <= 2^31), (0 <= M <= 59) i (0 <= S <= 59). At least one of numbers D, M or S will be greater then zero. All numbers are integers. There is a white space after the signs for degree and minute: ° and '.
0° 1’ 0”
7
13° 14’ 12”
5
Explanation for first example
• 1/2 of angle is 0° 0’ 30” – this is possible to measure.
• 1/3 of angle is 0° 0’ 20” – this is possible to measure.
• 1/4 of angle is 0° 0’ 15” – this is possible to measure.
• 1/5 of angle is 0° 0’ 12” – this is possible to measure.
• 1/6 of angle is 0° 0’ 10” – this is possible to measure.
• 1/7 of angle is 0° 0’ 8.5714” – this is first part Gondra can not measure.
So the answer is 7.
