诡异？

#include<bits/stdc++.h>
using namespace std;
const int N=1e5+5;
char m[N];
string s;
long long n,l,ans=1e15,now,h,c[500];
int main(){
	//freopen("P8013_4.in","r",stdin);
	ios::sync_with_stdio(0),cin.tie(0);
	cin>>s>>m+1>>c['A']>>c['C']>>c['G']>>c['T'];
	l=strlen(m+1);
	for(int i=1;i<=l;i++)s=' '+s;
	n=s.size()-1;
	for(int i=0;i<=n+l;i++){
		now=h=0;
		for(int d=i;d<i+l;d++)while(++now<=l&&m[now]!=s[d]&&h<ans)h+=c[m[now]];
		ans=min(h,ans);
	}cout<<ans;
	return 0;
