#include<bits/stdc++.h>
using namespace std;
int cnt[400010];
int nx[8]={-1,0,0,1,0,0,1,0};
int main() {
ios::sync_with_stdio(false);
int T;
cin>>T;
string t="nanjing";
while(T--) {
int n,k;
cin>>n>>k;
string s;
cin>>s;
s=s+s;
int j=0;
int i=1;
while(i<=n*2) {
if(s[i-1]==t[j]) {
j++;
if(j==7) {
cnt[i]=cnt[i-1]+1;
j=0;
}
else cnt[i]=cnt[i-1];
i++;
}
else if(j!=0) j=nx[j];
else {
cnt[i]=cnt[i-1];
i++;
}
}
int mx=0;
for(int l=0; l<=min(k,n-1); l++) {
mx=max(mx,cnt[l+n]-cnt[l]);
}
cout<<mx<<endl;
}
}
这程序好像有点Bug,我给组数据试试?
