Identical Toys Distribution: Given the number of T identical toys, find the number of ways W to distribute them among N children.
The first line will contain T and N separated by a space.
The first line will contain W. As W can be large, print the answer as modulo 1000000007
1 <= T, N <= 1000
Example Input/Output 1:
The three ways to disribute 2 toys among 2 children are (2,0) (0,2) (1,1)
from math import factorial t,n=[int(i) for i in input().split()] r=t+n-1 r1,r2,r3=factorial(r),factorial(t),factorial(r-t) print((r1//(r2*r3))%1000000007)
