I suppose then no-one really knows. Except for the last
six files, it was done by so many people, it is hard to say
that there wasn't any cheating going on.
It seems to me that they were at least legally replaced,
if not physically replaced. Testing code for
copyright infringement isn't easy, though. If I find
I=I+1
in two Fortran programs, that isn't much of an indicator
that one was copied from the other. It might not be
hard to write a program that would rearrange the code,
change variable names, and otherwise obscure the
original source. (Not the goal of most obfuscators.)
