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

Getting lots of TLE in Java. Any suggestion will be appreciated.

Test Cases are weak..

As like others,same algo in python got TLE while in C AC with 14 lines...It is the shortest C code written in Spoj by me...

Nice problem! Learnt something about how to cleverly avoid overflow errors.

it seems that 10^10 is not in test cases
my soln gives 1294379940242040320 stil ac.

at last got AC after a lots of TLE...if using c++ then use scanf and printf instead of cin and cout...this shows that scanf and printf are really faster...

Simple O(1) solution... Solve for small cases to get the answer...
