#include<iostream>

#include<vector>
using namespace std;
using LL = long long;

int main(){

    freopen("data.in", "r", stdin);

    cin >> T;
    while(T--){

        string s;
        cin >> s;
        int cnt = 0;
        bool ok = false;
        for(int i = 0; i < n; i++){
            if (s.substr(i, 4) == "CCPC"){
                cnt += 1;
            }
        }
        for(int i = 0; i + 2 < n; i++){
            auto t = s.substr(i, 3);
            if (t == "CCC"){
                auto tt = s.substr(i + 1, 4);
                if (tt != "CCPC"){
                    ok = true;
                    break;
                }
            }
            if (t == "CPC"){
                if (i == 0 or s[i - 1] != 'C'){
                    ok = true;
                    break;
                }
            }
            if (t == "CCP"){
                if (i + 3 == n or s[i + 3] != 'C'){
                    ok = true;
                    break;
                }
            }
        }
        cout << cnt + ok << '\n';
    }

}

这程序好像有点Bug,我给组数据试试?
