#include <iostream>

#include <vector>

void print(const std::vector<int>& vec, const std::string& message) {

    std::cout << message;

    for (int a : vec) {

        std::cout << a << " ";

    }

    std::cout << std::endl;

}

int main() {

    size_t size;

    std::vector<int> even;

    std::vector<int> odd;

    std::cout << "Enter the maximum number: ";

    std::cin >> size;

    for (size_t i = 1; i <= size; ++i) {

        if (i % 2 == 0) {

            even.push_back(i);

        } else {

            odd.push_back(i);

        }

    }

    print(even, "Even numbers are: ");

    print(odd, "Odd numbers are: ");

    return 0;
