思路：注意闰年的情况就行，还有就是最后输出的数要用long long 存

AC代码：

#include <iostream>#include <cstdio>#include <cstdlib>#include <algorithm>#include <queue>#include <stack>#include <map>#include <cstring>#include <climits>#include <cmath>#include <cctype>typedef long long ll;using namespace std;char cf[20];int lol[20];bool check(){    int i;    for(i=6; i<10; i++)    {        if(lol[i] != lol[i+1])        {            break;        }    }    if(i == 10)        return true;    for(i=6; i<10; i++)    {        if(lol[i] + 1 != lol[i+1])            break;    }    if(i == 10)        return true;    for(i=6; i<10; i++)    {        if(lol[i] - 1 != lol[i+1])            break;    }    if(i == 10)        return true;    int year = lol[3] * 1000 + lol[4] * 100 + lol[5] * 10 + lol[6];    if(year < 1980 || year > 2016)        return false;    int month = lol[7] * 10 + lol[8];    if(month <1 || month > 12)        return false;    int day = lol[9] * 10 + lol[10];    if(month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12)    {        if(day <1 || day > 31)            return false;    }    else if(month == 2)    {        if((year % 4 == 0 && year % 100 != 0) || year % 400 == 0)//这里把条件写成了year % 100 == 1,wrong了好多发，傻逼了        {            if(day < 1 || day > 29)                return false;        }        else if(day < 1 || day > 28)        {            return false;        }    }    else if(day <1 || day > 30)    {        return false;    }    return true;}int main(){    int t,n,a,b;    int i,j;    scanf("%d",&t);    while(t--)    {        scanf("%d",&n);        scanf("%d%d",&a,&b);        ll sum = 0;        for(i=0; i<n; i++)        {            scanf("%s",cf);            for(j=0; j<11; j++)            {                lol[j] = cf[j] - '0';            }            if(check())            {                sum += a;            }            else            {                sum += b;            }        }        printf("%I64d\n",sum);    }    return 0;}
