Have you felt bored when counting triangles?

Like TRICOUNT and TCOUNT2, we define the LEVEL of a triangle as in the following illustrative image:

And now we will continue defining the LEVEL of a hexagram. It's called level N hexagram if it’s joined by 12 triangles, each one is a level N triangle.

Task: All you have to do is to count all triangles in the level N hexagram.

Input

The first line of the input contains an integer T - the number of test cases and T lines follow. Each line contains an integer N which is the level of the hexagram in that test case.

Output

For each test case, you should write a separate line: the number of triangles in the level N hexagram. (All answers will fit within the range of a 64-bit positive integer)

Example

Input:
1
1

Output:
20
