Sort Array Algorithm

//  Sorting an array means to arrange its elements in increasing order.
//  Write a program to sort an array. Use the "selection sort" algorithm:
//  Find the smallest element, move it at the first position, find the
//  smallest from the rest, move it at the second position, etc.
