Reinitialize Object In-Place

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

using namespace std;

// Write your struct and placement new logic here

typedef struct{
    int level;
} Mode;



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

    // Write your in-place reinitialization logic here
    alignas(Mode) uint8_t buffer[sizeof(Mode)];
    Mode *ptr = new (buffer) Mode;
    ptr->level = firstLevel;
    
    ptr->~Mode();

    ptr = new (buffer) Mode;

    ptr->level = secondLevel;

    cout << ptr->level;

    ptr->~Mode();

    return 0;
}
