In PHP it's strrev(), in Rails it's .reverse, but most languages
don't have any string reverse function. Some have array reverse
functions that can be used on characters. I was thinking this
must be a major oversight but then it occurred to me, what would
you actually use string reverse for??? The only time I can think
I've seen it is in demos and lessons to turn "Hello World!" into
"!dlroW olleH". My question is; Is there a use for reversing a
string or is it completely pointless? There have been way more
answers that I had anticipated and not all of them were entirely
academic. I would have put money that no one could come up with
a legitimate example. I also didn't think I would learn anything
new but Mark Canlas' regex suggestion is just brilliant and I
look forward to the opportunity for it to prove itself. Thanks
to all.
