I need to write a subroutine that takes an array and shuffles it, however it has to ensure that the values in the new array are not in their original position. I came up with the following code and it appears to do what I want, though I am not completely sure yet. For whatever reason, the for loop doesn't work on the last element, so I just handle it outside the loop.
sub shuffleArray { my @array = @_; my $length = @array; for(my $i = 0; $i < $length - 1; $i++) { my $random = int rand($length -1); if ($i eq $random){$i--;} else{@array[$i,$random] = @array[$random, $i];} } my $random = int rand($length -2); @array[$random,$length -1] = @array[$length -1,$random]; return @array; }
