Chef has an old machine if the chef enters any natural number, the machine will display 1, 2, …n, n-1, n-2, n-3,…1 series and in next line prints sum of cubes of each number in the series. Chef wants to create a computer program which can replicate the functionality of the machine. Help the chef to code.

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- Each test case contains a single line of input, $N$. 

-----Output:-----
For each test case, output in a single line answer.

-----Constraints-----
- $1 \leq T \leq 50$
- $1 \leq N \leq 50$

-----Sample Input:-----
2
1
3

-----Sample Output:-----
1
45

-----EXPLANATION:-----
For 2) series will be 1, 2, 3, 2, 1 and the sum will be = 1 + 8 + 27 + 8+ 1
