Cmon, lambdas are just 1-time 1-expression functions if they aren't assigned to a variable...

The 10 in digits is for storing all possible digits (0..9), and each key stores the number of ocurrences of that digit in n

Nice recursion!

I solved that issue by using Math.ceil() instead of Math.floor, and then subtracting 1. This will give identical results in all cases except when the bounce takes you exactly to the window, in which case it'll subtract that bounce out.

lambda is for anonymous functions. Naming a lambda expression defeats the purpose.

Just ran into the same issue after switching to the C++17 variant. The C++14 one seems to be doing fine.

In my humble knowledge, I don't think there is O(26n) in Big-O notation. O(k*n) = O(n)

Okay then, thanks for explaining it.

It can be seen on the dashboard (home page) still.

Why would anyone read these comments before trying to solve it???

spoiler flag...

Didn't know how to rename groups and I didn't even think of www3., nice.

No problem, thank you for having kept me informed.
