example input: 6 2 1.0 3 1.0 4 1.0 3 0.5 5 0.678 9 0.87 First line means there will be 6 test cases. Each of the following 6 lines contains one test case (each test case represents one ping-pong tournament, and each test case is independent of the others). So the first line means there's a tournament with N=2 players, and P=1.0, which means that in any matchup, the higher-ranked player has a 100% chance of defeating the lower-ranked player. The fourth line means there's a tournament with N=5 players, and P=0.678, which means in any matchup, the higher-ranked player has a 67.8% chance of defeating the lower-ranked player.
