Problem Statement

Write a C++ program using `std::for_each` combined with a lambda expression to print all elements in a vector.

Input Format

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

Output Format

Print elements separated by a space.

Constraints

1 <= N <= 1000

Sample Input

4
10 20 30 40

Sample Output

10 20 30 40

Explanation

Lambdas integrate seamlessly with STL algorithms like `std::for_each` for concise in-place operations.

Starter Code

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    int n;
    if (std::cin >> n) {
        std::vector<int> vec(n);
        for (int i = 0; i < n; i++) std::cin >> vec[i];
        // Write your std::for_each lambda logic here
    }
    return 0;
}
