If two lists have intersection, then their last nodes must be the same one. So when pA/pB reaches the end of a list, record the last element of A/B respectively. If the two last elements are not the same one, then the two lists have no intersections. Analysis written by@stellari....

Both set(list1) and set(list2) convert the listslist1andlist2into sets, which are unordered collections of unique elements. Then, the&operatorreturns the intersection of the two sets. Example 4: Check Unique Elements between Two Lists

Set Intersection The intersection of two setsAandBinclude the common elements between setAandB. Set Intersection in Python In Python, we use the&operator or theintersection()method to perform the set intersection operation. For example, # first setA = {1,3,5}# second setB = {1,2,3}# pe...
You can first provide two expressions separated by a colon (:). After this, you’ll provide a for clause, and you can also include an optional if clause.To illustrate how dictionary comprehensions work, suppose that you have two lists of data, and you need to create a new dictionary ...
