#include <bits/stdc++.h>
using namespace std;
const int maxn=2e5+10;
int T;
int n,k;
string s;
int sum[maxn*2];
int main(){
ios::sync_with_stdio(0);
cin>>T;
while(T--){
cin>>n>>k;
cin>>s;
k=min(n-1,k);
for(int i=0;i<k;i++)
s.push_back(s[i]);
for(int i=6;i<s.size();i++){
sum[i]=sum[i-1]+(s.substr(i-6,7)=="nanjing");
}
int ans=0;
for(int i=0;i+n-1<s.size();i++)
ans=max(sum[i+n-1]-(i==0?0:sum[i-1]),ans);
cout<<ans<<endl;
}
return 0;
}
这程序好像有点Bug,我给组数据试试?
