Yes. And burn their cars to get their attention!
Asking someone to write a factorial algorithm before he knows WTF a
factorial "is", is either insane, or the ultimate demonstration of deliberate
lack of cooperation and coordination between departments.
I feel kind of strongly about this ever since, as a student, the physics people
expected me to use mathematics that I had not been taught yet...
;-)
I shall try to refrain from commenting on the concept of introducing
recursion into a first course in CS - I am too much tainted by my ability
to mentally "see" the stack growth in a small processor to be qualified
to comment.
