if not in t). The second one is O(len(t)) (for every element in t remove it from s). So care must be taken as to which is preferred, depending on which one is the longest set and whether a new set is needed.

In this method, we will iterate through the length of the list, and multiply every element at the corresponding index. We will append the result to a new list. For example, 1 2 3 4 5 6 7 8 9 lst1=[5,1,4] lst2=[2,3,1] ...
