Problem Descriptiona Relay is a race for, or more teams of runners. Each member of a team runs one section of the race. Your task is to help evaluate the results of a relay race.
You have to process several teams. The for each team is given a list with the running times for every sections of the race. You is to compute the average time per kilometer over the whole distance. That's easy, isn ' t it?
So if you like the "Fun" and challenge competing at this contest, perhaps you like a relay race, too. Students from ULM participated e.g. on the "SOLA" relay in Zurich, Switzerland. For more information visit Http://www.sola.asvz.ethz.ch/after the contest are over.
Inputthe first line of the input specifies the number of sections n followed by the total distance of the relay D in Kilom Eters. Safely assume that 1 <= n <= and 0.0 < D < 200.0. Every following line gives information about one team:the team number T (an integer, right-justified in a field of width 3) is followed by the n results for each of the sections, separated by a single space. These running times is given in the format "H:mm:ss" with an integer numbers for the hours, minutes and seconds, Respectivel Y. In the special case of a runner being disqualified, the running time would be denoted by "-:--:--". Finally, the data on every line was terminated by a newline character. Input is terminated by EOF.
Outputfor Each team output exactly one line giving the team's number T right aligned in a field of width 3, and the Averag E time for this team rounded to whole seconds in the format "M:ss". If at least one of the team's runners has been disqualified, output "-" instead. Adhere to the sample output for the exact format of presentation.
