Buying Integers
Let's assume that you have n integers, A1, A2, A3 … An
Let's define,
E = Number of pairs (i,j) such that i<j and ( Ai + Aj ) are even .
O = Number of pairs (i,j) such that i<j and ( Ai + Aj ) are odd .
D = | E-O |
That means, D = (E-O) if (E-O) ≥ 0 , -(E-O) otherwise .
Unfortunately, you do have n but those n integers are lost . You will have to buy them again. Before going to the market, you have decided that you will buy n integers in such a way that the value of D will be as small as possible, as you will have to pay D golden coins, to buy them.
Now,you are wondering, what that minimum D [Let's say it Dmin] will be .
Input
First line of the input file will contain the number of test cases, T ≤ 1000000, followed by T lines, each containing an integer n (1 ≤ n ≤ 109) .
Output
For each case, print the case number starting from 1 and Dmin for the value of n in that particular case. See the sample output for exact formatting.

Warning : Input file is huge, please use faster input and output methods (e.g. printf and scanf in C++) .
