I want to see how elegant a solution I can get in a functional
language, given that the problem description is not really elegant at
all. It has a few annoying exceptions to the normal rules, typical of
what one might get in a real specification from some client.
After taking a look at other solutions, I feel like I will have to explain
myself, so I’d better do that without prompting :)
- nothing was said about meaningful error messages, so I didn’t bother.
- I had decided against defining constants like
`supplier_markup_percentage_modification`
separately; `PremiumSupplierIDs` and markup table are defined locally
in the `calc`
function, too. The latter two issues are fixed in the next version, as
someone
may consider them to be against elegance.
- surprisingly, all solutions use explicit comparisons to determine the
product
category. While it is okay for continuous ranges of codes, it doesn’t
scale and
not really elegant. Fixed as well.
