//This program reads any number of track times (in mins and secs)
//    and allocates them to a CD with maximum time 74 minutes.
//The list of times is terminated by end of file
//e.g. three tracks with times 2:30, 1:52 and 4:15:
//
//2:30
//1:52
//4:15
//
//It prints a track list of selected tracks and the total time for the CD:
//
//Track 1 ( 2:30 )
//Track 2 ( 1:52 )
//Track 3 ( 4:15 )
//Total time: 8:37
//WARNING: All tracks are allocated
//This last message only occurs if the total time of all tracks is
//    less than 74 mins.
