Reset Fault Buffer

#include <iostream>
using namespace std;

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

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

    return 0;
}
