( 17604 ) A Middle of the Contest PROGRAMMING implementation 1000

B"Polycarp is going to participate in the contest. It starts at h_1:m_1 and ends at h_2:m_2 . It is guaranteed that the contest lasts an even number of minutes (i.e. m_1 % 2 = m_2 % 2 , where x % y is x modulo y ). It is also guaranteed that the entire contest is held during a single day. And finally it is guaranteed that the contest lasts at least two minutes. Polycarp wants to know the time of the midpoint of the contest. For example, if the contest lasts from 10:00 to 11:00 then the answer is 10:30 , if the contest lasts from 11:10 to 11:12 then the answer is 11:11 . The first line of the input contains two integers h_1 and m_1 in the format hh:mm. The second line of the input contains two integers h_2 and m_2 in the same format (hh:mm). It is guaranteed that 0 <= h_1, h_2 <= 23 and 0 <= m_1, m_2 <= 59 . It is guaranteed that the contest lasts an even number of minutes (i.e. m_1 % 2 = m_2 % 2 , where x % y is x modulo y ). It is also guaranteed that the entire contest is held during a single day. And finally it is guaranteed that the contest lasts at least two minutes. Print two integers h_3 and m_3 ( 0 <= h_3 <= 23, 0 <= m_3 <= 59 ) corresponding to the midpoint of the contest in the format hh:mm. Print each number as exactly two digits (prepend a number with leading zero if needed), separate them with ':'. "...
