Let’s define an easy sequence F. Where

$ F(1) = 1 $

$ F(2X) = F(X)^2 + 1 $

$ F(2X+1) = F(X) \times F(X+1) + 2 $

Here X is a positive integer. The first few elements of the sequence are 1, 2, 4, 5, 10, 17, 22, 26, 52, 101.

Now given a value of $ F(X) $, can you compute X?

The first line of the input is a positive integer T (T ≤ 100), the number of test cases. Then T lines follow.

In each line there will be a value of $ F(X) $ (1 ≤ $ F(X) $ ≤ 10⁹). It is guaranteed that for every $ F(X) $ in the input, there exists a valid X.

For each case print a line in “Case I: X” format where I is the test case number and X is the corresponding value for the given $ F(X) $ in the input.
