Problem Statement

Write a C++ program using `std::transform` to square every element in a vector.

Input Format

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

Output Format

Print transformed vector elements separated by a space.

Constraints

1 <= N <= 1000

Sample Input

4
1 2 3 4

Sample Output

1 4 9 16

Explanation

Applies a unary/binary operation across a range and stores results in a destination range.

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::transform logic here

    }
    return 0;
}
