问题标题: 酷町堂：1559 数据处理80分，求神犇。

这是我的错误代码(WA两个点):

#include <bits/stdc++.h>
using namespace std;
int a[100000];
int pd2(int m)
{
    if(m%400==0||m%4==0&&m%100!=0)
    {
        return 29;
    }
    return 28;
}
int pd(int n,int m)
{
    if(n==4||n==6||n==9||n==11) return 30;
    else if(n==2) return pd2(m);
    return 31;
}
int main()
{
    int year,month,day,d,e,year1,month1,day1,d1,e1,ans=0,n,ans1=0;

        if(day>pd(month,year))
        {

            month++;

                year++;
            }
        }
    }
    sort(a+1,a+n+1);
    ans1=d1*60+e1-(d*60+e);
    ans=ans*1440+ans1;
    ans++;

        }
