#include <bits/stdc++.h>
using namespace std;
int t,n,k;
string S,T="nanjing";
int op[400011],s[400011];
int main()
{
cin>>t;
while(t--){
cin>>n>>k;
k=min(k,n-1);
cin>>S;
for(int i=0;i<k;++i)S+=S[i];
for(int i=0;i<n+k;++i){
op[i]=0;
}
for(int i=0;i+T.size()-1<S.size();++i)
{
bool flag=1;
for(int _=0;_<7;++_)if(S[i+_]!=T[_])
{
flag=0;
break;
}
op[i]=flag;
}
s[0]=0;
for(int i=0;i<n+k;++i){
s[i+1]=s[i]+op[i];
}
int ans=0;
for(int i=n;i<=n+k;++i)
{
ans=max(ans,s[i]-s[i-n]);
}
cout<<ans<<"\n";
}
}
这程序好像有点Bug,我给组数据试试?
