AutoIt script to execute on key combination event

     For the Programming section of SecurityOverride, you are required to make a script to resolve a task, given a random input, in a short time, 10-15 seconds.  The method I've used for all the challenges:  I've written an AutoIt  script that:

• stays active when run
• after a keyboard combination is pressed:
  
  • copies the selected text into clipboard
  • gets it, and executes a function on it
  • puts the result in the clipboard

Example for challenge1:


         In order to complete Programming Challenge 1, you must code a script that will reverse the string below, while maintaining the first letter at the beginning.
         Example: chicken -> cnekcih

 Autorun program on Ctrl+C event (for SecurityOverride programming)

#comments-end 

HotKeySet("^{F1}", "Solve")
Global $input

While 1
 Sleep(10000)
WEnd


Func Solve()
 GetInput()
 ParseInput()
 Exit(0)
EndFunc

Func GetInput()
 Send("^{c}")
 $input = ClipGet()
EndFunc

Func ParseInput()  
 Local $a = StringToASCIIArray($input)
 Local $len = StringLen($input)
 Local $i, $j = 1
 Dim $rez[$len]
 
 $rez[0] = $a[0]
 For $i = $len-1 to 1 Step -1
   $rez[$j] = $a[$i]
   $j = $j + 1
 Next
 
 ClipPut(StringFromASCIIArray($rez))
EndFunc

; cnekcih
