Question

Write code in main that will read in 6 ints and store them into the list values. When you read a positive number it should be added to the back of the list. When you read a negative number, it should be inserted at the front of the list.
Example: Given input 5 2 -4 3 -1 6, you would build up:

5
5 2
-4 5 2
-4 5 2 3
-1 -4 5 2 3
-1 -4 5 2 3 6

#include <iostream>
#include <list>

using namespace std;

template <class T>
void print(const list<T>& v) {
for (auto myIt = v.begin(); myIt != v.end(); ++myIt) {
cout << *myIt << " ";
}
cout << endl;
}

int main() {
list<int> values;

//Do not modify anything on or above the line below this
//YOUR_CODE_BELOW

//YOUR_CODE

//YOUR_CODE_ABOVE
//Do not modify anything on or below the line above this

print(values);
}

#include <iostream>

using namespace std;


template<class T>
void print(const list<T> &v) {
    for (auto myIt = v.begin(); myIt != v.end(); ++myIt) {
        cout << *myIt << " ";
    }
    cout << endl;
}

int main() {
    list<int> values;


    //Do not modify anything on or above the line below this
    //YOUR_CODE_BELOW

    int num;
    for (int i = 0; i < 6; ++i) {
        cin >> num;
        if (num < 0) {
            values.push_front(num);
        } else {
            values.push_back(num);
        }
    }

    //YOUR_CODE_ABOVE
    //Do not modify anything on or below the line above this

    print(values);
