G Four penguins of different heights are standing in a row. Their owner would like to put them in order so that their height increases from left to right. The owner makes the following rearrangements in sequence:
If the first two on the left are out of order, switch them.
If the middle two are out of order, switch them.
If the last two on the right are out of order, switch them.
Will the penguins be in order after these steps are applied?
If not, is there a way to modify this method to guarantee that it always arranges the penguins in order?
