#include <bits/stdc++.h>
using namespace std;
int main()
{
cin.tie(0)->sync_with_stdio(0);
int tc;
cin >> tc;
while (tc--)
{
int n;
string s;
cin >> n >> s;
s = '$' + s + "$$";
bool buy = false;
int ans = 0;
for (int i = 0; i + 3 <= n; i++)
{
char a = s[i], b = s[i + 1], c = s[i + 2], d = s[i + 3], e = s[i + 4], f = s[i + 5];
buy |= a != 'C' && b == 'C' && c == 'P' && d == 'C';
buy |= b == 'C' && c == 'C' && d == 'P' && e != 'C';
buy |= b == 'C' && c == 'C' && d == 'C' && (e != 'P' || f != 'C');
ans += b == 'C' && c == 'C' && d == 'P' && e == 'C';
}
cout << ans + int(buy) << '\n';
}
}
这程序好像有点Bug，我给组数据试试？
