(In reply to now for the computer solution to the right problem by Charlie)

Ah, right you are, Charlie!  I got the last 2499 digits right, but my logic for getting the 2500th from the right was flawed, for just the reason you suggested.


I'll have to give a little more thought to how to do it using pencil and paper.
