Hello (list:-)
Using list comprehension, I am building a list of tuples that I want
unique and sorted.
Is this a correct way of doing it:
Result = sets:to_list(sets:from_list([ {A,B} || {_X,_Y,A,_Z,B} <-
MyList]))
Then sort the Result.
The alternative would be to use one of the lists functions to copy
elements into a new list and testing first at each insert if the
element is already present.
What is best?
Thanks,
Alex
