[Tutor] an error on recursion depth (fwd)

[Danny Yoo]

Hi Marta,

Do not send Python questions to 'tutor-admin@python.org'.  That address
only is meant for administrative stuff (subscription questions), and only
reaches a paltry three people.

You probably meant to send to tutor@python.org, so I'll forward the
message to the mailing list for you.

Best of wishes to you!

Subject: an error on recursion depth

Hi list,
my program stops with this:

RuntimeError: maximum recursion depth exceeded

Why? I used the program in Python 1.5.2.: never happened. I think I already
used it also for exactly the same task (same parameters, same complexity)
also in 2.1. It's the first time it breaks.
How can I avoid it?

thank you

PS:(down I attach the whole final part: the fisrt line is repeat alot of
times and then you have the ending part)
