empty string should either be tested against by a fixed test or ruled out in the description

expected x to equal y means that your code returned x but y was the correct answer. it is your code that returns this when the input is an empty string.

Nice Kata!

For real, C helps you understand algorithms better.

Solved in c++, nice kata.

I haven't checked whether your code fails or passes, but you are definitely getting a bunch of warnings (which are not errors, though they appear in stderr in the output). Write your code in a proper IDE with linting support (e.g. VS Code + RustAnalyzer) to see all the slightly silly thing's your code is doing.

I just solved this and there are not errors in sample or submission tests.

Rust random-test failing but anyways resulting as a correct solution.

First time using rust....... This was not the right way to learn this language unlike all the others I have learned. However, this challenge was very fun and I'll be redoing it in a language I know better.

Amazing Kata, this one goes directly to my collection, It's a gem! Thanks!!

one line solutions is bad and not clear ᶻ 𝗓 𐰁 ᶻ 𝗓 𐰁

Nice Kata, Thanks!

Enjoyable kata !

How does a beginner go about understanding this regex? I can follow the parenthesis and understand the asterisks, but it's difficult to grasp the logic behind searching for the given sets of 0s and 1s. I can't even understand how to normally solve this kata without a regex, so I feel bad for getting stuck on this 4 kyu when I've completed others at this difficulty level.
