Maybe your solution is generated by starting with the second character instead of the first character or something?

Sorry, I meant the sample tests, not just the examples. That way it helps people to do some basic debugging before pressing "attempt".

Might be worth adding examples for + and -, in addition to * and //?

Would it be helpful for me to read through and approve this? I've not done this stuff on Codewars before - not sure on the process - but this is now 4 months old and looks good at first glance.

What is the issue with that? That was the intent for the kata - to make use of the corpus created by brute forcing the first tests.

Is that the original message or the encrypted message? If it is the encrypted version then "FRGHZDUV KHDGTXDUWHUV" could plausibly be an encrypted "CODEWARS HEADQUARTERS". It certainly isn't intended that some of the messages don't contain that string.

Yes - the diagram is definitely helpful. I just completed this kata about colouring a map: https://www.codewars.com/kata/5f88a18855c6c100283b3773. I think that kata is a good example (and also the harder version of the same kata) of using detailed examples to demonstrate the rules.

Great Kata! The test examples are all well-constructed to show all the things my code had to deal with, and the 5 assumptions in the Kata description were really clear. However, I do think the Kata description could be a bit friendlier to people with no knowledge of RNA molecules. It would also be helpful to explain WHY 'AUGCUUUUUUGCAUG' should give 4 as the output. And maybe one more explained example from the test cases. I actually interpreted everything in the description correctly, but it would have been good to check my understanding on some examples.

Extremely satisfying end to the series of Scyscraper Sudoku solvers. This is the first time I have ever truly tried to optimise my code and look for ways to make it faster. My data science background means that I am usually content to just get the job done at some point in the next couple hours :). Obviously most of the otpimisation was finding better general strategies (e.g. improve on the brute force I implemented for the 4x4 kata), but I also learnt a huge amount about testing and iterating to find what worked best. Some of the results were surprising. Thank you!
