Dear all,
I was wondering if I could divide all elements of a vector by the
max element of that vector.
I checked the STL references and found transform, for_each and
lately BOOST_FOREACH, but transform and for_each algorithms are not
suited since I have another argument to supply to the functions,
namely max_element. I wondered if this is possible or not through
the standard.
BOOST_FOREACH seemed the best option to me. But I wondered :)
Everybody is supposed to do their own homework.

That was the question, without a loop, is this possible?
Yes, but you'd have to use recursion. As to whether it's possible
using 'transform', 'bind', 'divides', etc., you have your reply, but
keep in mind there is always a loop whether *you* write it or it is
written *for you* in the library routine.
I could not find the answer in my references,
I made the example quickly, hope it is error free!
I didn't check it. But I'd probably moved the 'if(fabs(max)))' out
of the loop and changed the 'max' to something else (since there
are functions named 'max' in 'std').
