Sorry, you're right I did only take one loop ...

Back, when the system was developed (and almost until recent
days) Writing was a time consuming thing - and cost a lot of
resources (space on coins and seals, paper, ink, etc), so
the whole system was designed to save resources - call it a
kind of compression algorythm - instead of writing 5 strokes,
just write two, different placed and further, 4 strokes could
be replaced by 3 when using the subtraction rule.
Today we are most exopsed to roman numerals from movies (and
newer productions) where a) space is no longer a consiferation,
b) Numbers with _more_ Numerals look more impressive and
c) correct writing isn't exactly the main goal.

For classic Roman Numerals, noone, but within this contest the
Numerals have been restricted :)
(BTW: this x1000 rule is the orign why we put a '.' (or ',' in
the US) between each 3 digits)

THats exactly my point - tofulfill the contest we needan exact
description of the result - it's the usual thing - the customer
gives an unclear description, besed on a lot of 'you-know' termns
and when we do the software he is shocked by the result :)
