Cool, and yet another thing I have to learn to make use of: "yield from".

It took me way too long to wrap my brain around this. I understood that k was counting up while n was counting down, but I had to run it myself and add print statements everywhere for me to realize that next(number) wouldn't actually add to k every single time (this felt like a "duh" moment once I got it). Calling next(number) will yield the next number from map(int,str(k)) if there's still something to yield, or will add to k if it finishes that loop to go to the next number.
