Answer 1

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

int main () {
    int arr1[] = {19, 2, 6, 8, 12};
    int arr2[] = {30, 1, 5, 9, 13, 20};
    std::vector<int> vec(11);

    std::sort(arr1, arr1 + 5);
    std::sort(arr2, arr2 + 6);
    std::merge(arr1, arr1 + 5, arr2, arr2 + 6, vec.begin());

    for (auto const &val: vec) {
        std::cout << val << " ";  
    }
}
