0) Count(N) -> print 1, 2, 3, 4, ... N


1) Make a function that computes the factorial of n.
	fac(3) = 6     // 3*2*1
	fac(5) = 120   // 5*4*3*2*1


2) Make a method that prints n spaces and then a given character.
	stars(count=5, letter="*") -> "     *"
	stars("@', 12)             -> "            @"


3) Using recursion and no loops, make a method that find the largest element from a list
	smallest([1,2,3,2]  -> 3
	smallest([5,2,1,17) -> 17
	smallest([]) does not crash!


4) Using recursion and no loops, make a method that computes A to the Bth power
	power(3,5)            -> 243
	power(base=2,exp=3)   -> 8
	power(exp=0, base=5)  -> 1
	power(0,0)   -> anything you want


13) Using recursion and no loops, make a method that returns a string backwards
	backwards("Hello") -> "olleH"
	backwards("") -> ""
