很水的一个题，按照题目要求照着写出来代码就可以AC

#include<stdio.h>#include<math.h>#include<string>#include<cstring>#include<string.h>#include<algorithm>#include<iostream>using namespace std;int main() {int m1, m2, r1, r2, r3;char str[210];while(scanf("%d%d", &m1, &m2) != EOF){r1 = r2 = r3 = 0;cin >> str;int len = strlen(str);for(int i=0; i<len; i++){if(str[i] == 'A')r1 = m1;else if(str[i] == 'B')r2 = m2;else if(str[i] == 'C')m1 = r3;else if(str[i] == 'D')m2 = r3;else if(str[i] == 'E')r3 = r1 + r2;else if(str[i] == 'F')r3 = r1 - r2;}cout << m1 << "," << m2 << endl;}return 0;}
