Problem code: CB01
All submissions for this problem are available.
This is a very simple problem. Given the value of N and K, you need to tell us the value of the binomial coefficient C(N,K). You may rest assured that K <= N and the maximum value of N is 1,000,000,000,000,000. Since the value may be very large, you need to compute the result modulo 1009.
The first line of the input contains the number of test cases T, at most 1000. Each of the next T lines consists of two space separated integers N and K, where 0 <= K <= N and 1 <= N <= 1,000,000,000,000,000.
For each test case, print on a new line, the value of the binomial coefficient C(N,K) modulo 1009.
