Reinitialize Object In-Place

#include <iostream>
#include <cstdint>
#include <new>

using namespace std;

// Write your struct and placement new logic here
struct Mode
{
    int level;
};

int main() {
    int firstLevel, secondLevel;
    cin >> firstLevel >> secondLevel;

    // Write your in-place reinitialization logic here
            alignas(Mode) std::byte buffer[sizeof(Mode)];

            Mode* ptr = new(buffer) Mode{firstLevel};
            //ptr->level = firstLevel;
            ptr->~Mode();

            ptr = new(buffer) Mode{secondLevel};
           // ptr->level = secondLevel;
            ptr->~Mode();
            std::cout <<ptr->level;

            


    return 0;
