Smart Pointers in STL Containers

Medium Smart Pointers

Problem Statement

Write a C++ program storing `std::unique_ptr` instances inside a `std::vector` to manage dynamic objects safely.

Input Format

First line: N. Second line: N space-separated integers.

Output Format

Print elements managed by vector of unique pointers separated by a space.

Constraints

1 <= N <= 100

Sample Input

4
10 20 30 40

Sample Output

10 20 30 40

Explanation

Storing smart pointers in containers prevents memory leaks and manual heap cleanup loops.

Starter Code

#include <iostream>
#include <vector>
#include <memory>

int main() {
    int n;
    if (std::cin >> n) {
        // Write your vector of unique_ptrs logic here
    }
    return 0;
}
