For a given N, prints the sum of even and odd integers of the first N natural numbers.

First line of the input contains an integer T which denotes the number of test cases. Then T test cases follow.  Each test case contains a single line containing N.

Output: 
For each test case, print space separated sums of even and odd integers of the first N natural numbers respectively.

Constraints:
1 <= T< = 200
1<=N<=10000

Example:
Input:
2
1
6 
Output:
0 1
12 9
