It's great! I've had community members point me in the right direction after already "solving" it incorrectly. It really makes you think about it. You have to expand your test cases and really come up with a better solution.
Not to say it isn't difficult especially if you expect the problem to be described perfectly accurately.
I don't need a perfect instruction set, but dang if the examples couldn't be better sometimes. Like
sixteenwas in there to show it only counted for 6, but nothing with overlapping text.The example for me immediately showed my overlap bug with “eightwo”. There aren’t too many other ways to make this ten words overlap. 🙂
The problem is the example is actually
eightwothreewhich comes out as83so 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
1threeightis meant to be18or13. If your solution replaces the words to numbers from left to right you end up with13as the value but it's meant to be18.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
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
