This diff is colored to make it clear what parts of the output are wrong. Green indicates things in the correct output that you are missing, red indicates things in your output that shouldn't be there.

The ↵ character refers to newlines, so the green ↵ character refers a newline you are missing in your output and the red ↵ refers to a newline you need to remove from your output.
