#165907 - Reminding of Achilles and the turtoise
Responding to: ???'s previous message
I think it is a quite interesting problem, since the way it is attacked so very much affects how hard it is to solve.

I obviously did not count "bounces" or try to solve the sum of an infinite series. This problem is a bit similar to the old problem of Achilles and the tortoise:
http://en.wikipedia.org/wiki/Zeno's_paradoxes

Edit: As I see it, there are three ways to solve:

1) The elegant way just involving the head

2) Solving limes 120*sum 1/(5^n) for n=0->inf, i.e. 120*(1 + 1/5 + 1/25 + 1/125 + ...)

3) Getting a compiler and the fastest computer in town.
