Print the number from 1 to entered number and from entered number to 1 using 1 loop,c++

Hello, I am stuck with one problem in c++, I have to enter a number and output needs to be from 1 to entered number and from entered number to 1, but using only one loop. I can't figure it out, what is the catch? Example: 1 2 3 4 4 3 2 1

Maybe this might help #include <iostream> using namespace std; int main() { int num,key; cin >> num; key = num *2 +1; for (int i=1; i<key; ++i){ if(i <= num){ cout << i << endl; } else { cout << key -i << endl; } } return 0; }
