12.4.2 (arrangements)<BR></FONT><BR></DIV>
<DIV></DIV>Hi,<BR><BR>I solved Exercise 12.4.2 (the arrangements problem) after
writing clear purpose statements and writing a few different auxiliary
functions. It was an eye-opener for relying on wishful thinking and trusting
that recursive calls would work as intended.<BR><BR>Exercise 17.6.5 (gift-pick)
calls for us to use 'arrangements' again, and after changing the variable names
to make it a general-purpose function, I realized that I'm still having trouble
visualizing a flow-chart. I don't want to spoil the experience by emailing my
solution to people who may still be working on the problem, but could someone
who has a good handle on the problem please review my code and help me visualize
the flow?<BR><BR>Thanks,<BR>Mike<BR></BODY></HTML>
