Problem
You have been invited to the popular TV show "Would you like to be a millionaire?". Of course you would!
The rules of the show are simple:If you win the bet, your total amount of money increases by the amount you bet. Otherwise, your amount of money decreases by the amount you bet.
Given M, P and X, determine your probability of winning at least $1000000 if you play optimally (i.e. you play so that you maximize your chances of becoming a millionaire).
Input
The first line of input gives the number of cases, N.
Each of the following N lines has the format "M P X", where:
Output
For each test case, output one line containing "Case #X: Y", where:
Answers with a relative or absolute error of at most 10^{6} will be considered correct.
Limits
1 ≤ N ≤ 100
0 ≤ P ≤ 1.0, there will be at most 6 digits after the decimal point.
1 ≤ X ≤ 1000000

Case #1: 0.500000

In the first case, the only way to reach $1000000 is to bet everything
in the single round.
In the second case, you can play so that you can still reach $1000000 even if you lose a bet. Here's one way to do it:
