Playing with text/strings. This is a short WinForms app with an input box - yes I've used a name input but it could be any string - and an output box that shows the string in reverse once the button is clicked.
There are two reverse methods available - one is a standard reversal although this only really works with utf16 char set and the other uses Xor to enable both a faster action and also to enable it to use the full UTF32 char set.
