Karel dreams of climbing mountains. Teach her to get to the top of a mountain of any height. For example, for the following mountain:

Karel should climb to the top and leave a flag (a beeper) at the summit as shown bellow:

You can assume:

  • Karel starts on the bottom left of the world, facing east.
  • There is one space (on the left and the right) between the mountain and the world boundry.
  • The mountain is at least one square high.
  • The mountain consists of steps that are 1 space big up/down and left/right.<
