in reply to Reversing string case

What did you try so far? At which point did you fail? Have you looked at the functions uc and lc?

    The code i could think of 
    
if ($string =~ /[A-Z]+/){
        $string = lc $string;
}else{
        $string = uc $string;
}

      Your code lower-cases the whole string if a singe uppercase character is found. Is that what you want? What should happen to strings with mixed case?

      Also you ignore all non-ASCII upper case letters.
