What is the simplest way to make a union or an intersection of Sets in Java? I've seen some strange solutions to this simple problem (e.g. manually iterating the two sets).

I have a list of lists: lists = [[1,4,3,2,4], [4,5]] I want to flatten this list and remove all duplicates; or, in other words, apply a set union operation: desired_result = [1, 2, 3, 4, 5] W...

I have list of ranges which all of the ranges in that list has the same start and stop, but not the same step. eg: rr = [range(0, 10, 2), range(0, 10, 3)] Of course, the list can contain more than...

Is there any difference between using the reversed union or intersection operators on sets in Python? for instance, s & z corresponds to s.__and__(z) z & s corresponds to s.__rand__(z) ...

I am trying to merge sets defined in a set and this is what I have now a = frozenset([1,3,4]) b = frozenset([1,2,3,4,5]) s = set() s.add(a) s.add(b) merged = set(itertools.chain.from_iterable(s)) ...

Consider the following sets of probabilities (the three events are NOT mutually exclusive): 0.05625 success, 0.94375 failure 0.05625 success, 0.94375 failure 0.05625 success, 0.94375 failure H...

Since a code example is worth a thousand words I'll start with that: testList = [1,2,2,3,4,5] testSet = map sumMapper $ tails testList where sumMapper [] = [] sumMapper (a:b) = sumMap a b sumMa...
