    My 6 months of coding knowledge and understanding in 1 hr 15 minutes. To those people who had trouble understanding hashcode, equals, comparator, comparable: just keep trying, you will understand it. Comparator is really important because sometimes to solve a Q, you need to sort the input data in a particular way, which can be easily done with the help of comparator.

Also, you made Comparator, and Comparable look so easy. Thanks for this tutorial, I'm having an interview within a few days and I hope I can crack it.
