`Problem A: Buttons <https://atcoder.jp/contests/abc124/tasks/abc124_a>`_
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The idea of this problem is to chose the maximum button during the first button press. During the second button press, we will chose the maximum after subtracting 1 from the button we just pressed. The code bellow simulates this process:

.. code-block:: C++
    :linenos:

    #include <bits/stdc++.h>

    using namespace std;

    int main () {
      
      int a, b;
      cin >> a >> b;
      
      if ( a > b) {
          cout << max(a,b) + max(a-1,b);
      } else {
          cout << max(a,b) + max(a,b-1);
      }
       
      return 0;
      
    }
