Recursive and iterative

How can I improve the following code using both Recursive and iterative approaches ?

the code is only recursive , also needs timings how long it will take to move n number of discs

Move disk 1 from tower A to tower C Move disk 2 from tower A to tower B Move disk 1 from tower C to tower B
