Chinese Football Lottery provided a “Triple Winning” game. The rule of winning was simple: first select any three of the games. Then for each selected game,bet on one of the three possible results–namely W for win,T for tie(引き分け)、and L for lose.There was an odd assigned to each result. The winner’s odd would be the product(乗)of the three odds times 65.
For example, 3 games’ odds are given as the following:
W T L 1.1 2.5 1.7 1.2 3.1 1.6 4.1 1.2 1.1
To obtain the maximum profit, one must buy W for the 3rd game, T for the 2nd game, and T for the 1st game. If each bet takes 2 yuans, then the maximum profit would be (4.1×3.1×2.5×65%−1)×2=39.31 yuans (accurate up to 2 decimal places). Input Specification:
Each input file contains one test case. Each case contains the betting information of 3 games. Each game occupies a line with three distinct odds corresponding to W, T and L. Output Specification:
For each test case, print in one line the best bet of each game, and the maximum profit accurate up to 2 decimal places. The characters and the number must be separated by one space. Sample Input:
1.1 2.5 1.7 1.2 3.1 1.6 4.1 1.2 1.1
Sample Output:
T T W 39.31
