我就蒯了一份代码随便改了改怎么就过了？？？
从这道题目蒯的
代码：
#include<iostream>
#include<cstdio>
#include<cstdlib>
#include<cstring>
#include<cmath>
#include<algorithm>
using namespace std;
#define MAX 505
#define ull unsigned long long
const int base=2333;
ull h1[MAX],h2[MAX],pw[MAX];
char ch[MAX],s[MAX];
int P[505],tot,n,m,ans;
bool f[505][MAX];
int main()
{
scanf("%s",s+1);n=strlen(s+1)+1;s[n]='?';
pw[0]=1;for(int i=1;i<MAX;++i)pw[i]=pw[i-1]*base;
for(int i=1;i<=n;++i)h1[i]=h1[i-1]*base+s[i];
for(int i=1;i<=n;++i)if(s[i]=='*'||s[i]=='?')P[++tot]=i;
int T;scanf("%d",&T);
while(T--)
{
memset(f,0,sizeof(f));f[0][0]=1;
scanf("%s",ch+1);m=strlen(ch+1);ch[++m]='#';
for(int i=1;i<=m;++i)h2[i]=h2[i-1]*base+ch[i];
for(int j=0;j<=tot;++j)
{
if(s[P[j]]=='*')
for(int i=1;i<=m;++i)f[j][i]|=f[j][i-1];
for(int i=0;i<=m;++i)
{
if(!f[j][i])continue;
int l1=i+1,r1=i+(P[j+1]-P[j])-1;
int l2=P[j]+1,r2=P[j+1]-1;
if(h2[r1]-h2[l1-1]*pw[r1-l1+1]==h1[r2]-h1[l2-1]*pw[r2-l2+1])
{
if(s[P[j+1]]=='?')f[j+1][r1+1]|=f[j][i];
else f[j+1][r1]|=f[j][i];
}
}
}
ans+=f[tot][m]?0:1;
}
cout<<ans<<endl;
return 0;
}
