#include <iostream>
using namespace std;

int main() {
    int code;
    cin >> code;

    // Write your safe delete + pointer reset logic here
    int* faultcode = new int(code);
    cout << *faultcode << " ";
    delete faultcode;
    faultcode = nullptr;
    if (faultcode== nullptr){
        cout << "OK";
    }
    else {
        cout <<"NOT_OK";
    }
    return 0;
