Input: given n and m

Task : For given n and m we have to calculate (n+m-2)C(n-1) mod 1000000007 where c is binomial coefficient

Constraints : 1 <= T <= 10^3

1 ≤ m,n ≤ 10^6

My solution

Accepted solution

For the given test case(Which I is used in ideone)

1) Both are passing in ideone

2) My solution is failing on hackerrank(Segmentation fault) other one is passing on hackerrank
