Hi Kai,

 

my goal is not to reduce line count but not have three times the same code. every time you want to edit this code, you must edit it three times...

 

we can't remove the last foreach loop because it is the one which allow to check all codes in defined range.

 

And this code deserve 5 stars as the code is well explained, is generic enough to be used by everyone and performance gain is high.
