#include <bits/stdc++.h>
using namespace std;
using LL = long long;
using PII = pair<int , int>;
void solved() {
int n , k;
cin >> n >> k;
string s;
cin >> s;
k = min(n , k);
if(s.size() < 7){
cout << "0\n";
return ;
}
string s1 = "nanjing";
for(int i = 0 ; i < k ; i ++ )
s += s[i];
int ans = 0;
for(int i = 0 ; i + 7 <= n ; i ++ ){
string a = s.substr(i , 7);
if(a == s1) ans ++;
}
int res = ans;
for(int i = n - 6 ; i + 7 <= s.size() ; i ++ ){
string a = s.substr(i , 7);
if(a == s1) ans ++;
a = s.substr(i - n + 6 , 7);
if(a == s1) ans --;
res = max(res , ans);
}
cout << res << "\n";
}
int main(){
ios::sync_with_stdio(0);
cin.tie(0);
cout.tie(0);
int t = 1;
cin >> t;
while(t -- )
solved();
return 0;
}
这程序好像有点Bug,我给组数据试试?
