If at any point pA meets pB, then pA/pB is the intersection node. To see why the above trick would work, consider the following two lists: A = {1,3,5,7,9,11} and B = {2,4,9,11}, which are intersected at node '9'. Since B.length (=4) < A.length (=6), pB would ...

Intersecting Lists with set() If the order of your elements is not important and if you don’t need to worry about duplicates then you can use set intersection: In the first example, you convert both lists to sets, intersect them and then output them again as a list. The order in the...

You can intersect two sets:set1 = {"Roger", "Syd"} set2 = {"Roger"} intersect = set1 & set2 #{'Roger'}You can create a union of two sets:set1 = {"Roger", "Syd"} set2 = {"Luna"} union = set1 | set2 #{'Syd', 'Luna', 'Roger'}...
