想问下各位，为什么测试点过不去

Question

#include<bits/stdc++.h>
using namespace std;
int main(){
    string s[4];
    char day,hour,minute,tag;
    int t;
    for(int i=0;i<4;i++){
        cin>>s[i];
    }
    for(int i=0;i<s[0].length();i++){
        if(s[0][i]==s[1][i]&&(s[0][i]>='A'&&s[0][i]<='G')){
            day=s[0][i];
            t=i;
            break;
        }
    }
    for(int i=t+1;i<s[0].length();i++){
        if(s[0][i]==s[1][i]){
            hour=s[0][i];
            break;
        }
    }
    for(int i=0;i<s[2].length();i++){
        if(s[2][i]==s[3][i]&&((s[2][i]>='a'&&s[2][i]<='z')||(s[2][i]>='A'&&s[2][i]<='Z'))){
            minute=s[2][i];
            tag=i;
            break;
        }
    }
    string week[7]={"MON","TUE","WED","THU","FRI","SAT","SUN"};
    cout<<week[int(day-'A')]<<" ";
    if(isdigit(hour)){
        printf("%02d",int(hour-'0'));
    }
    else printf("%02d:",int(hour-'A'+10));
    printf("%02d",tag);
}
