Analysed a lot, but it deserves. To know what happens in the function with jmp rdi is the key, after that you can write a program with a more effective algorithm (can be found on the web easily if you really know what happens), the result will appear soon.

I thought that while it was fun to RE the function you describe, I wasn't a huge fan of just searching for a faster algorithm to copy-paste.

Just try to understand program on smaller data set ;)

Oh god! Finally!

Is the answer to this challenge a data type ULL ?

Lets be honest, this is hardcore

Hahaha TKOA makes some awesome challs...
