当 `mm` 个位为0时 `mmm` =0 则 `mmm`-1 就炸了 建议加一个特判应该能过

AC code:
```cpp

#include <cstring>
using namespace std;
const string Date[12]=\
{"31", "28", "31", "30", "31", "30", "31", "31", "30", "31", "30", "31"};

{"01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12"};
string s, m, d;
int mm, dd, tot, tot1, tot2, tot3;
int main( ) {
cin >> s;
m = s.substr(0,2);
d = s.substr(3,2);
mm = (s[0] - '0') * 10 + (s[1] - '0');
dd = (s[3] - '0') * 10 + (s[4] - '0');
if(mm > 0 && mm < 13) {
tot = 0;
if(Date[mm - 1][0] < d[0] || (Date[mm - 1][0] >= d[0] && Date[mm - 1][1] < d[1])) {
tot++;
}
cout << tot;
}
else
if(mm > 0&& mm % 10 != 0){//加一句mm%10!=0即可
tot1 = 1;
int mmm = mm % 10;
if(Date[mmm - 1][0] < d[0] || (Date[mmm - 1][0] >= d[0] && Date[mmm - 1][1] < d[1]) || dd == 0) {
tot1++;
}
tot2 = 0x3f3f3f;

tot2 = 1;
int mmm = mm % 10 + 10;
if(Date[mmm - 1][0] < d[0] || (Date[mmm - 1][0] >= d[0] && Date[mmm - 1][1] < d[1]) || dd == 0) {
tot2++;
}
}
cout << min(tot1, tot2);
}
else {
tot1 = 1;
int mmm = 1;
