Hi All,
I've inherited some code that I need to integrate into some existing
code. The author of the old code is using a construct I don't
understand. There are things like:
if (X - [a, b]) = [] then ...
where "X" is a set and "a" and "b" are valid members of that set. My
understanding of sets is that this should be the same as:
if (a in X) or (b in X) then...
but it isn't, because if I replace the first "if" with the second,
the program behavior changes.
Can someone help me with my conceptual gap and explain what the first
"if" is saying? Thanks.
Regards,
