#include <bits/stdc++.h>
using namespace std;
typedef long long ll;
typedef long long lint;
typedef pair<int, int> pii;
typedef pair<ll, ll> pll;
int L, K;
string s;
void exe() {
cin >> L >> K >> s;
vector<bool> yes(L, true);
for (int i=0; i<L; i++) {
for (int j=0; j<7; j++) yes[i] = yes[i] && (s[(i+j)%L] == ("nanjing"[j]));
}
int sum = 0;
for (int i=0; i<L; i++) sum += yes[i];
K = min(K, L);
int ans = 0;
for (int i=0; i<=K; i++) {
int now = sum;
for (int j=L-6; j<L; j++) now -= yes[(i+j)%L];
ans = max(ans, now);
}
cout << ans << '\n';
}
int main()
{
ios_base::sync_with_stdio(false); cin.tie(NULL);
int tc;
cin >> tc;
for (int i=1; i<=tc; i++) exe();
}
这程序好像有点Bug,我给组数据试试?
