3. Calculate the eating time of users from the beginning to queue up to finish. The beginning and end time will be passed in "hh mm ss" format. The three numbers are separated by spaces.

Sample: Input1: Read in using Scanner 12 30 20 12 35 26 Output1: 5m6s Input2: Read in using Scanner 12 30 40 12 55 40 Output2: 25m 5m6s Input2: Read in using Scanner 12 30 40 12 55 40 Output2: 25m Input3: Read in using Scanner: 12 30 40 12 30 40 Output3: Os (The beginning and end time won't be across a day and the end time is not earlier than beginning time. If the minute and second both equal O, then print "Os"; if one of them equals 0, then only print the other like "80m", "525")
