I really thought about making a function too but in the end just went with a script with a hard coded max value. Our solutions are very similar. This was definitely a tough one to get some clean code.

How did you know the max value?

Did you get a result? My solution is very similar - brute force looping and looking for a result that is meaningful.

Yes, I just failed to post the result in this gist. I'll update it in a few.

How did you know the max value?

I guessed tbh. I initially started with something much larger but once I saw the solution had 12 in the interval I changed the max to that.
