If only one input is given the function should sort in ascending order. The function is supposed to use a for loop that is nested in a while loop. The for loop should compare the vector value by value, switching the two as necessary to complete the ascending order. The while loop stops the function once the ascending or descending condition is met.

Here is a hint complete with pseudocode (for sorting in ascending order)
<<http://en.wikipedia.org/wiki/Bubblesort>>
In the pseudocode example, replace the "repeat loop" with a "while loop" and you basically have it.
I'll leave the descending part to you.
