Sorting an array

There's an array of values from 1 to n. It isn't sorted. We have to sort it, but there are only to ways to move: third element to beginning or last element to beginning. How to do that ?

So what's the algorithm? Or are you just solving that one case?
What about
if (third < first) {
 swap (third)
} else if (last < first) {
 swap (last)
} else swap (min(third, last))
