Problem Description

Mr. Frog has n sticks, whose lengths are 1,2, 3 ⋯n respectively. Wallice is a bad man, so he does not want Mr. Frog to form a triangle with three of the sticks here. He decides to steal some sticks! Output the minimal number of sticks he should steal so that Mr. Frog cannot form a triangle with
any three of the remaining sticks.

 

Input

The first line contains only one integer T ( T≤20), which indicates the number of test cases. 

For each test case, there is only one line describing the given integer n ( 1≤n≤20).

 

Output

For each test case, output one line “Case #x: y”, where x is the case number (starting from 1), y is the minimal number of sticks Wallice should steal.

 

Sample Input

3 4 5 6

 

Sample Output

Case #1: 1 Case #2: 1 Case #3: 2
