I decoded both parts, and it makes perfect sense, but then when i submitted i only got 0 and for the highlight of the first wrong, there is none. why is that?
[A few people have submitted solutions with a chunk missing from the end of the decrypt. If there is too much wrong with a submission the checker marks it as zero and withholds feedback to prevent attempts to fish for a solution. Might be worth checking that you have decrypted all of it? Harry]
