poj 3941 Hideyuki is allowed by his father Ujisato some 1000 yen bills every month for his pocket money. In the first day of every month, the number of bills is decided as follows. Ujisato prepares n pieces of m-sided dice and declares the cutback k. Hideyuki rolls these dice. The number of bills given is the sum of the spots of the rolled dice decreased by the cutback. Fortunately to Hideyuki, Ujisato promises him to give at least one bill, even if the sum of the spots does not exceed the cutback. Each of the dice has spots of 1 through m inclusive on each side, and the probability of each side is the same. In this problem, you are asked to write a program that finds the expected value of the number of given bills.
