#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?
