UJ  Uncle Jack
Dear Uncle Jack is willing to give away some of his collectable CDs to his nephews. Among the titles you can find very rare albums of Hard Rock, Classical Music, Reggae and much more; each title is considered to be unique. Last week he was listening to one of his favorite songs, Nobody’s fool, and realized that it would be prudent to be aware of the many ways he can give away the CDs among some of his nephews.
So far he has not made up his mind about the total amount of CDs and the number of nephews. Indeed, a given nephew may receive no CDs at all.
Please help dear Uncle Jack, given the total number of CDs and the number of nephews, to calculate the number of different ways to distribute the CDs among the nephews.
Input
The input consists of several test cases. Each test case is given in a single line of the input by, space separated, integers N (1 <= N <= 1000) and D (0 <= D <= 2500), corresponding to the number of nephews and the number of CDs respectively. The end of the test cases is indicated with N = D = 0.
Output
The output consists of several lines, one per test case, following the order given by the input. Each line has the number of all possible ways to distribute D CDs among N nephews.
Example
Input: 1 20 3 10 0 0 Output: 1 59049

Test Cases are loose

This is the only option for c++ users.

c++ users can use <boost/multiprecision/cpp_int.hpp>

Let's see, I *could* try really hard to fit this into 512B of c/c++ code. I *could* rage about how this will never work in Java. OR I could submit it in python. Thumbs down; useless problem is useless.

i dont see the point of 512 bytes :
