MODERATORS
You can't just replace the first letter either, because depending on the order of your replacements, you could be replacing the end of another number. (Encountered this exact problem trying to optimize my solution.)
I replaced the second letter, none of them overlap 2 letters.
Clever
As long as you replace any spelled out numbers from left to right it should work
2oneight- if you replace from left to right you get21ightor21. This doesn't work for part 2 as the answer should br28.We're talking about just the first letter, so
2oneight—>21neight—>21n8ight
