#include <iostream>
using namespace std;

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

    // Write your safe delete + pointer reset logic here
    int* fault = new int(code);
    cout << *fault << " ";

    delete fault;
    fault = nullptr;

    (fault == nullptr) ? cout << "OK" : cout << "NOT OK";
