#include <cstddef>

struct Buffer {
    int* data;
    size_t size;

    Buffer(size_t n) : data(new int[n]), size(n) {}
    ~Buffer() { delete[] data; }

    // write the move constructor here
    Buffer(Buffer&& other) noexcept;
};

Implement the move constructor: it should steal other's resources and leave other in a valid, empty state.

Buffer::Buffer(Buffer&& other) noexcept
    : data(other.data), size(other.size) {
    other.data = nullptr;
    other.size = 0;
}
