CodeChefRating 2383Open on judge ↗

As we all know, Binomial Coefficient C(n, r) is defined by the following formula. Also define S(n) as follows. Note that n will be provided to you as an input parameter. Since S(n) can be very large, please print it modulo (109 + 7). Input - The first line contains a single integer T representing the number of test cases. - Each of the next T lines contains an integer n. Out
