*sort](https://en.wikipedia.org/wiki/Selection_sort) implementation using
*swapping
* @details
* The selection sort algorithm divides the input vector into two parts: a sorted
* subvector of items which is built up from left to right at the front (left) of
* the vector, and a subvector of the remaining unsorted items that occupy the
*rest of the vector. Initially, the sorted subvector is empty, and the unsorted
*subvector is the entire input vector. The algorithm proceeds by finding the
*smallest (or largest, depending on the sorting order) element in the unsorted
*subvector, exchanging (swapping) it with the leftmost unsorted element (putting
*it in sorted order), and moving the subvector boundaries one element to the
*right.
