Ordering T-shirts

Working in a boutique folding and putting in order T-shirts according to their sizes seems very easy. But is it really so simple? Given n objects of different sizes, how many different arrangements can be done using relationships ‘<’ and ‘=’? For instance, with 2 objects, A and B, we have 3 possible arrangements: A=B A<B B<A With 3 objects, A, B and C, you must conclude that 13 different arrangements exist: A=B=C A=B<C A<B=C A<B<C A<C<B A=C<B B<A=C B<A<C B<C<A B=C<A C<A=B C<A<B C<B<A Input The first line of the input contains an integer, t, indicating the number of test cases. For each test case, one line appears, that contains a number n, 1 ≤ n ≤ 11, representing the number of objects. Output For each test case, the output should contain a single line with the number representing the different arrangements you can do with n objects. Sample Input 4 1 2 3 4 Sample Output 1 3 13 75
