 这题思路有的，就是要注意细节。

#include<iostream>
#include <string.h>
using namespace std;

int a1=0, a2=0, b1=0, b2=0;
int a_arr[3], b_arr[3];
char ch[3]={'C','J','B'};

int biggest(int arr[], int len){
	int max=-1, max_index=-1;
	for(int i=0; i<len; i++){
		if(arr[i]>max || (arr[i] == max && ch[i] < ch[max_index])){
			max = arr[i];
			max_index = i;
		}
	}
	return max_index;
}

void winner(char j, char y){
	if(j=='C' && y=='J'){
		a_arr[0]++;
		a1 ++;
		b2 ++;
	}else if(j=='J' && y=='B'){
		a_arr[1]++;
		b2 ++;
		a1 ++;
	}else if(j=='B' && y=='C'){
		a_arr[2]++;
		b2 ++;
		a1 ++;
	}else if(j=='J' && y=='C'){
		b1 ++;
		a2 ++;
		b_arr[0]++;
	}else if(j=='B' && y=='J'){
		a2 ++;
		b1 ++;
		b_arr[1]++;
	}else if(j=='C' && y=='B'){
		a2 ++;
		b1 ++;
		b_arr[2]++;
	}
}

int main(){
	int n;
	char a, b;
	cin >> n;
	for(int i=0; i<n; i++){
		cin >> a >> b;
		winner(a, b);
	}
	cout << a1 << " " << n-a1-a2 << " " << a2 << endl;
	cout << b1 << " " << n-b1-b2 << " " << b2 << endl;
	cout << ch[biggest(a_arr, 3)] << " " << ch[biggest(b_arr, 3)];
	return 0;
}
