Demonstrate how to strip leading and trailing whitespace from a string. The solution should demonstrate how to achieve the following three results:

For the purposes of this task whitespace includes non printable characters such as the space character, the tab character, and other such characters that have no corresponding graphical representation.

Let's start with the solution:

s = "   ars   longa   "
"("+strtrim(s)+")"
  (ars   longa)

"("+strltrim(s)+")"
  (ars   longa   )

"("+strrtrim(s)+")"
  (   ars   longa)

"("+stritrim(s)+")"
  (   ars longa   )
