Hammer scissors PAT B 1018 (C language)

Hammer 1018 scissors (20 minutes)

We should be able to play "hammer and scissors" game: they both give gesture, as shown in Figure outcome of the rules:

Now given the two men clash records, statistics of both wins, flat, negative number, and the two sides are what give the greatest chance of winning gesture.

Input format:
Enter line 1 gives a positive integer N (≤10 ^ 5), i.e., both the number of confrontation. Then N rows, each row gives information confrontation, i.e., the gesture and B sides at the same time is given. C stands for "hammer", the representative J "scissors", B stands for "cloth", the first letter represents a party, on behalf of the second party, there is an intermediate space.

Output Format:
output the first and second lines are given A, B wins, flat, negative number, separated by an inter-digital space. Line 3 shows two letters represent A, B wins the highest number of gestures, there is an intermediate space. If the solution is not unique, the minimum solution alphabetically output.

Sample input:

10
C J
J B
C B
B B
B C
C C
C B
J B
B C
J J

Sample output:

5 3 2
2 3 5
B B

Write super long, super long changed, writing sucks, long and boring ...

Finally I found it a mistake, added the little getchar () on line 60;

写的超级长，改了超级久，写的很烂，又臭又长...
最后发现就一个错误，在第60行少加了一句getchar();
至于为什么要加这一句，请移步https://blog.csdn.net/weixin_44562957/article/details/104117402
