Harry Potter dreams himself in a witchy magic shop, it contains an infinite amount of Golden Snitch. He is allowed to select n Golden Snitch. There are Golden Snitch of k different sizes. From each size there are also infinitely many Golden Snitch. Harry Potter wants to have at least one snitch of each size, but still there are a lot of possibilities for his selection. In his effort to make a decision he wakes up. Now he asks your help to develop a python program to find out how many possibilities for his selection he would have had. Assume that Golden Snitch of equal size can't be distinguished, and the order of the Golden Snitch is irrelevant.
