Finding the index of the minimum element in a subarray

There are many different ways to sort the cards. Here's a simple one, called selection sort, possibly similar to how you sorted the cards above:

Find the smallest card. Swap it with the first card.
Find the second-smallest card. Swap it with the second card.
Find the third-smallest card. Swap it with the third ...
