Reads in a sequence of strings from standard input; quicksorts them; and prints them to standard output in ascending order. Shuffles the array and then prints the strings again to standard output, but this time, using the select method.

Rearranges the array so that a[k] contains the kth smallest key; a[0] through a[k-1] are OrderHelper.Less than (or equal to) a[k]; and a[k+1] through a[N-1] are greater than (or equal to) a[k].

Rearranges the array in ascending order, using the natural order.
