Super Big Snake says "we need to filter snakes with "a" length greater than 3 and less than 5" but actually means to say "match snakes with "a" length greater than or equal to 3 and less than or equal to 5" (or "greater than 2 and less than 6"). Hate Even Numbers says to match numeric strings whose first digit is not even, but actually means to match all strings whose first character is not an even digit. There are other cases (e.g. in Password Hint) where a character is referred to as a digit. Good game...

For example, in 4 Leading A "Now, the goal is to capture strings starting with A and optionally containing one digit." Test Case 33A yes But this does not start with A Test Case 3A3 yes Same here Deleting demo......

It says it needs to match all cases on the right, and despite the level being called Decimal Numbers, there's cases like "." and "0.0.0" and "a.1". My regex should've worked but didn't and the solution regex that they tell you is "\A-?\d+\.\d+\Z", which should not account for any of the cases I listed above. Right? ...Right??...

Why the heck would you flat out include links to various AI that can solve the problems for you? The point is to learn, not copy and paste prompts into AI. It's bad enough that you are using AI generated music. Gonna be a pass from me
