Construct Sensor Packet Placement

#include <iostream>
#include <cstdint>
#include <new>
#include <type_traits>
using namespace std;

// Write your struct and placement new logic here

struct SensorPacket 
{
    int id;
    int value;
};

int main() {
    int index, id, value;
    cin >> index >> id >> value;

    // Write your pool construction code here
    alignas(SensorPacket) std::byte buffer[3 * sizeof(SensorPacket)];

    SensorPacket* packet = new (buffer + index) SensorPacket{id, value};

    cout << packet->id << " " << packet->value;

    packet->~SensorPacket();

    return 0;
}
