You are given an equation of the form x1+x2+...+xN=K. You need to find the total number of positive integral solutions of this equation.
The first line of the input contains an integer T, denoting the number of test cases. Then T test case follows. Each testcase contains a single line that denotes the equation.
Print the total number of positive integral solutions.
1 <= T <= 100
1 <= K <= 25
2 <= N <= 10
