I also coded an equivalent solution for the problem in the old MSDOS basic. (That's the 16 bit app of 1980s vintage.)  It ran in 56 sec. Is there a flaw in my coding, or is Python really this slow in this particular application. MSDOS Basic usually runs at a snails pace compared to Python.

Are you sure you wouldn't like to share with the class?  I'd be interested
in seeing your approach...
