What is Selection Sort?

Quick Preview: Selection Sort repeatedly finds the minimum element from the unsorted portion and places it at the beginning. It maintains two subarrays: sorted and unsorted.

Why learn it: While not the fastest, selection sort is simple and helps understand the concept of finding minimum/maximum elements.
