Now let's try some fancy things!

We will randomly generate two collections. Collection A would have smaller size between 10 and 1000 , and Collection B would have larger size betwwen 10000 and 500000 . Then we will compute the intersection of these 2 Collections in 2 ways, by iterating over Collection A(and B in the Hash Set), and vice versa.

We will run each computation method 30 times to measure its performance and determine the difference in time cost between the two approaches.

The result will be...
