Problem Statement

Write a C++ program using `std::unique_ptr` to manage dynamic memory safely without manual deallocation.

Input Format

A single integer N.

Output Format

Print the value managed by `std::unique_ptr`.

Constraints

-100000 <= N <= 100000

Sample Input

420

Sample Output

420

Explanation

`std::unique_ptr` provides exclusive ownership of a heap-allocated resource, automatically freeing memory when it goes out of scope.

Starter Code

#include <iostream>
#include <memory>

int main() {
    int n;
    if (std::cin >> n) {
        // Write your unique_ptr implementation here
    }
    return 0;
}

Limits

  • Time Limit: 1s
  • Memory Limit: 256MB

Embedded C Programming

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
