Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Thanks to the Codewars community for this brilliant kata — a fun deep dive into hex, binary, and XOR logic!

Description does not mention how to handle empty strings/strings with no hex characters.
(At least in Python this expects
0to be returned).Approved
Description doesn't mention that we have to convert hexadecimal characters into decimals first.

One of the worst kata descriptions in the history of kata descriptions! Until I read the discourse I had no idea what I was actually supposed to do.
What does XOR mean?
Ok... so I took
e, d, f. Now I XORewithd??? How does that work? It only works if you ASSUME these characters still have HEX meaning.Whatever, I'm not gonna argue over semantic details. All I was trying to say was that the instructions looks incomplete / confusing. That sentiment is supported by comments here on discourse. But as I said, if you think it's fine, then it's fine. Good night :P
