Love a good cypher

As with others I took a bit of time to get q1 and q3 right, but I'm just bad at reading long descriptions and went with the wikipedia definition instead of the hint outlined in the kata. Overall this was a nice kata and I enjoyed it.

I don't think I solved this in the intended way

Only took me a few minutes but the solution felt very satisfying.

Hey that was great. Took a while to understand what was being asked though, I'm not very good at reading long descriptions.

I've found bitwise operators really useful in the past for storing booleans and it was fun working out how to do this one.

Glad I did all those regex katas so I can unnecessarily use regex for things like this.

Pretty good once I actually understood it.

These katas are helping me discover SQL features I never could have dreamed of.

dont know why everyone is ragging on this kata, I thought it was fine. The columns to merge on are a bit confusing I suppose.

Good lord that took me HOURS to work out. A nice easy 7 kyu that won't take long I thought. How wrong I was.
Looks like I ended up with some massively overcomplicated formula compared to others looking at the solutions, but still works. Could have probably reduced it down but I was a bit sick of it by the end.

First 3 kyu I've solved. Wrote a pretty long solution but got through it reasonably quickly and was genuinely surprised when it actually worked. Immediately thought of a way I can do it without ugly edge case handling after finishing but oh well. Good stuff.

Learnt something new with this Kata, very cool, thanks!

Fun kata, thanks!
