#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
const int N=1e6+3;
int n,k,nb[N];
char ch[N];
bool Chk(int x)
{

for(int i=0;i<=6;i++)t+=ch[x+i];
return t=="nanjing";
}
void Solve()

for(int i=0;i<n;i++)ch[i+n]=ch[i];
if(n<7){cout<<0<<endl;return;}
for(int i=0;i<2*n;i++)nb[i]=nb[i-1]+Chk(i);
for(int i=0;i<=min(n,k);i++)ans=max(ans,nb[i+n-7]-(i==0?0:nb[i-1]));
cout<<ans<<"\n";
}
int main()
{
ios::sync_with_stdio(0),cin.tie(0),cout.tie(0);
int T;cin>>T;
while(T--)Solve();
}
这程序好像有点Bug，我给组数据试试？
