Well, I'll be honest:) I posted the puzzle on a local C/C++ mailing
list, and somebody (without giving a correct replacement) answered
that ~ prints 21 '-'. BTW, you can test the level of a list with this
puzzle. TLUG won ;)

But if you think about it, inversion of a number has something to do
with changing its sign...
