1014 福尔摩斯的约会

我感觉是这题出的有问题，第二个只说了字母，并没有说第二个大写字母...为啥就得从第一个大写字母后面开始检索呢。

#include <bits/stdc++.h>
using namespace std;
map<int,string> mp = {{1,"MON"},{2,"TUE"},{3,"WED"},{4,"THU"},{5,"FRI"},{6,"SAT"},{7,"SUN"}};
int main() {
	int d,h,m;
	string s1,s2,s3,s4;
	cin>>s1>>s2>>s3>>s4;
	int len = min(s1.size(),s2.size());
	int count = 0; 
	for(int i=0;i<len;i++){
	    if(count==0 && s1[i]==s2[i] && s1[i]>='A' && s1[i]<='G'){
	    	count++;
	    	d=s1[i]-'A'+1;
	    	continue;
		}
		if(count==1 && s1[i]==s2[i] && s1[i] >='0' && s1[i]<='9'){
			h=s1[i]-'0';
			break;
		}
		if(count==1 && s1[i]==s2[i] && s1[i]>='A' && s1[i]<='N'){
			h=s1[i]-'A'+10;
			break;
		}
	}
	//后面两个
	len = min(s3.size(),s4.size());
	for(int i=0; i<len; i++) {
		if(s3[i]==s4[i] && isalpha(s3[i]) && isalpha(s4[i])) {
			m=i;
			break;
		}
	}
	printf("%s %02d:%02d",mp[d].c_str(),h,m);
	return 0;
}
