The problem is the example is actually eightwothree which comes out as 83 so if you replace from start to finish the example passes but the solution is incorrect.

At this point you're just complaining that the edge case is not highlighted in red.

I think it's the right amount of pointers to make you aware of the issue without straight up telling you.

I'm not really sure how to interpret your comment but I'll try my best. The edge case that causes some solutions to fail does not have any definition on how to handle it on the problem page. In other words, it does not state anywhere whether the correct interpretation of 1threeight is meant to be 18 or 13. If your solution replaces the words to numbers from left to right you end up with 13 as the value but it's meant to be 18.

The example answers don't cover this but you will realise something is wrong if you run it against your full problem. Community has been very helpful on providing pointers.

Just don't replace, or replace only the first letter with the numeral

[–] DaleGribble88 1 points 1 year ago (2 children)

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.

As long as you replace any spelled out numbers from left to right it should work

[–] stifle867 1 points 1 year ago (1 children)

2oneight - if you replace from left to right you get 21ight or 21. This doesn't work for part 2 as the answer should br 28.

We're talking about just the first letter, so

2oneight —> 21neight —> 21n8ight
