#include <bits/stdc++.h>
using namespace std;
const int N=200050;
char s[N];
int pref[N];
string nanjing="nanjing";
int main(){
int t;
scanf("%i",&t);
while(t--){
int n,k;
scanf("%i %i",&n,&k);
scanf("%s",s);
if(n<nanjing.size()){

continue;
}
for(int i=0;i<n;i++){
bool ok=true;
for(int j=0;j<nanjing.size();j++){

if(ok)pref[i+1]++;
}
int ans=0;
int sz=n-nanjing.size()+1;
for(int i=0;i<min(k+1,n);i++){
int sum;
if(i+sz<=n){
sum=pref[i+sz]-pref[i];
}else{
sum=pref[n]-pref[i]+pref[i+sz-n];
}
ans=max(ans,sum);
}
printf("%i\n",ans);
}
return 0;
}
这程序好像有点Bug,我给组数据试试?
