Hi Dustin, thanks for your reply!
I didn't ask for suggestion because I'm sure there are so many solutions to this test!
More performant, more declarative, more functional, more more more :)
Someone may even find an O(1) version of this, I don't know :D
As you said the problem is doing it there, under pressure. I like to write elegant code, I like approaching problem methodically, I do like these problems. But my method it just doesn't work in a context like that. Not when the stakes were so high.
@poof – speak truth my man!
