WAYS - PATHS

Consider a square matrix of order m (m+1 rows and m+1 columns). At each step you can move one step to the right or one step to the top. How many possibilities are to reach (m, m) from (0, 0)?

Input

The first line consists of an integer t, the number of test cases. Each test case consists of a single integer m, the order of square matrix.

Output

For each case print the number of possibilities of reaching the point (m, m) from (0, 0)

Constraints

1 ≤ t ≤ 10

1 ≤ m ≤ 14

Example

Sample Input:
3
1
2
3

Sample Output:
2
6
20

How can people can do in just 77B !!! Just somehow reached 107B.

I was thinking of a DP solution and then found the source limit ..Read some stuff and realized it can be solved using combinatorics..

got every test case right from 1 to 14 ... but still getting WA ,,,. somebody help ...please!!
2015-07-05 21:50:52
Are you mad :(
only
public class .... public static void main
take more than 120B
remove JAVA from languages or the 120B Limit.
