MINCOUNT - Move To Invert

no tags 

A triangle made of coins of height h is as follows
It has h coins at the base and h-1 coins one level above base and so on.(Coins are placed as shown in the figure below)
And at the top most level there will be only one coin
Now given h the task is to invert this triangle by moving minimum number of coins. For example when h=4 triangle is
Invert
For h=4 at least 3 coins must be moved to invert it.

Input

In the first line N will be given and then N lines follow with each line having a integer which is the height of triangle in that test case.00≤h<1010;

Output

For each test case output in a seperate line the minimum number of moves required to invert the triangle. Output fits in long long data type

Example

Inputt:
1
3

Output:
2

It's weird, my AC solution gives 1294379940242040320 for 10^10... looks like test cases are weak.

Answer for 100 is 1683....HOW..Could somebody pls explain?

how to minimise the time?
its showing time limit exceeded :(

test cases are weak.... output for 10^10 4368837285860298922 still got AC

:)AC gives=>
10000000000 = 16666666668333333333

top row = 1, second row = 2 3, third row = 4 5 6, fourth row = 7 8 9 10 Solution: move 7 to the left of 2, move 10 to the right of 3, move 1 below 8&9

not getting how it is inverted by moving 3 coins.......
