MINCOUNT  Move To Invert
A triangle made of coins of height h is as follows
It has h coins at the base and h1 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
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<10^{10};
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

~30000 testcases per file.
