Hello,

I have this code : https://gist.github.com/RoelofWobben/7c08680797d1d9f84436653a0e4edd3b
as� my solution to a AoC challenge.

But the last test `testIsNice`� is still� outputting the wrong output.
The right output is :�� `ugknbfddgicrmopn ` and `aaa` Someone who can think with me where I make a thinking error so that the right output is seen. Regards, Roelof
