Medium STL Iterators

Solve in Playground →

Problem Statement

Write a C++ program using `std::istream_iterator` and `std::ostream_iterator` to read and write vector elements via streams.

Input Format

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

Output Format

Print elements separated by a space using stream iterators.

Constraints

1 <= N <= 1000

Sample Input

3
10 20 30

Sample Output

10 20 30

Explanation

Stream iterators connect algorithms and containers directly to input/output streams.

Starter Code

#include <iostream>
#include <vector>
#include <iterator>

int main() {
    int n;
    if (std::cin >> n) {
        // Write your stream iterator logic here

    }
    return 0;
}
