Method 3: In this method we set() the larger list and then use the built-in function called intersection() to compute the intersected list. intersection() is a first-class part of set.
WebAs far as performance, #1 will probably perform better in most cases, since it will dump all of one list into a hash table and then do an O(1) lookup for each element in the other list. Two exceptions to this that I can think of are (1) if the lists are very small, then building the hash table data structure might not be worth the overhead and ...
