#include<bits/stdc++.h>
using namespace std;
int work(string s){
int ret=0;
int n=s.size();
for(int i=0;i+7<=n;++i){
if(s.substr(i,7)=="nanjing") {
ret++;
}
}
return ret;
}
void solve(){
int n,k;
cin >> n >> k;
string s;
cin >> s;
int ans=work(s);
for(int i=1;i<=min(k,7);++i){
s=s+s[0];
s=s.substr(1,n);
ans=max(ans,work(s));
}
cout<<ans<<"\n";
}
int main(){
ios::sync_with_stdio(0);
cin.tie(0);
int t;
cin >> t;
while(t--){
solve();
}
return 0;
}
这程序好像有点Bug,我给组数据试试?
