sorting int array with only 3 elements

Question

I have this array:

int [] myarray =  {17, 6, 8};

What is the optimal way to sort this array, in pseudocode?

Thanks!

Answer 1

Slightly more efficient version than the unrolled bubble sort, not optimal, but still quite simple

if (el1 > el2) Swap(el1, el2)
if (el2 > el3) {
   Swap(el2, el3)
   if (el1 > el2) Swap(el1, el2)
}
