##### Canadian Computing Competition: 2011 Stage 2, Day 1, Problem 1

After your great performance in computing competitions, you have been admitted to the University of Waterloo. In your first term there, full of enthusiasm, and wanting to increase your streak of success in academic competitions, you decide to take part in the Putnam competition.

Three months later, you get to know your score. It is very good, so you decide to add it to your CV. However, the released results only include the average rank for each of the attained scores. You think that might not be enough information, and want to include the exact range in which your score falls (i.e. if there are 25 people with scores better than yours, and 3 people tied with you, the range would be 26-29).

Furthermore, you want to build a program that would handle possible future situations in which the range of the scores, as well as the number of contestants, have greatly increased. You also want your program to work even if the scores are not necessarily given to you in order.
