12. (Extra Credit) Don't do this one until you've worked on all others first! This is worth only a few points and is MUCH harder than the other problems. Define f(0)=1 and f(x) = 7f(x-1). Find the last 10 decimal digits of f(10). You'll probably want to use Python; make sure you explain the technique you used!
