TRICOUNT - Counting Triangles
We define the LEVEL of a triangle as in the following illustrative image:
Task: Your task is very easy. All you have to do is to count all triangles in the biggest one (Level N).
Input
The first line of the input contains an integer T (T ≤ 10000) - the number of test cases and T lines follow. Each line contains an integer N (1 ≤ N ≤ 106) which is the level of the triangle in that test case.
Output
For each test case, you should write a seperate line: the number of triangles in the biggest one (Level N). (All answers will fit within the range of a 64-bit integer)
Example
Input:
3
1
2
3
Output:
1
5
13

tried a lot to derive the formula!! finally had to check the net :((( |

enjoyed a lot deriving formula ... i will recommend to derive it yourself rather than coping from net, else no point of doing this question |

There is no diagram of level 3, it makes it difficult to understand what the pattern is. |

And at all the people commenting about the formula online, the whole point is to figure out the formula yourself otherwise there's not much point, is there? Heh. |

Horribly written question. There should have been some explanation of how the levels are defined instead of randomly providing a pattern for powers of 2. |
