Timo is a hero of LOL. Etond pretty like this hero too. Timo can place the Mushroom in the road. Timo have N (0 < N < 100) Mushrooms, And there are M (0 < M < 100) grass over here. Timo want to place at least K (0 < k < 100) Mushrooms in each grass. Now Timo can't count the all sulutions, please write a program to help Timo count all sulutions. If there are no sulutions here print "-1".
There are muticase here. For each case, there are 3 integers. n, m, k.
For each case, count all the sulutions, Timo can place.
