After an unsuccessful attempt at claiming power peacefully,
Borko has decided to tear down Mirko’s village hall, which was
built for him out of cardboard by his loyal servants.
For this he will use Mirko’s microprocessor (which was
stolen from him by Borko’s friend Zvonko), a bucket of water
and a bag of sodium. He will enter the time of the “explosion”
into the microprocessor, and it will drop the sodium in the
water after the time is up.
Borko knows the current time and when he wants the
explosion. He is not very fond of arithmetic and Zvonko is
currently playing with marbles in his back yard so he can’t
Write a program that calculates the time to the explosion
(this is the time Borko will enter into the microprocessor).
The time Borko wants is at least one second and at most 24
The first line of input contains the current time in
hh:mm:ss format (hours, minutes, seconds). The hours will be
between $0$ and
$23$ (inclusive) and the
minutes and seconds between $0$ and $59$. The second line contains the
time of the explosion in the same format.
Output the desired time on a single line, in the same format
as the times in the input.
