You are correct, a list is not a set. A list is a list of things, that can be there multiple times. A set is a set of things, where nothing can be twice. So take a look at Data.Set Am 25.03.2015 14:55 schrieb "Shishir Srivastava" < shishir.srivastava@gmail.com>:
Hi,
Can someone please explain why this results in error -
[] `elem` [1,2,3]
Shouldn't the empty set by definition be the element of all sets including a non-empty set ?
I am assuming 'Lists' are different from 'Sets' in Haskell, if yes, is there a separate module for dealing/working with sets ?
Thanks, Shishir Srivastava
