How was day one for everyone? I was surprised at how tricky it was to get the right answer for part two. Not the usual easy start I've seen in the past. I'd be interested to see any solutions here.

Really cool idea! Just bad that it increases the submit time every failed attempt. I have to wait now 10 minutes on the 2nd question. + In what order?

For example: oneight CAN be 1ight or on8

Is it sorted by 1-9 or one - nine or first in word first served?

I think this is my currently issue, and i cant go through and sadly my patience of submitting every try every 10 mins has ended and i just lost it.

The delay is just so unnecessary...

It’s normally not so tricky on the first day, and the examples also normally do a much better job of guiding you away from wrong approaches so the increasing delay is intended to ensure you aren’t just spamming poorly tested answers.

The task in part two could be better written as “find the first occurrence of a digit in the string (either as a digit or as a word), and then separately find the last occurrence of a digit (either as a digit or as a word again) then compose these two digits”. Thinking of it like that should help you identify where your problem lies.
