Our customer is the Monte Vegas Casino on Planet Diabloblo. Extremely arrogant guys, but they pay well. They've asked us to make an automatic mailing list for potential customers. Don't worry. The junior programmer (you) has been assigned a simple task: create a (last name, salary) dictionary and remove any entries for people whose salary is less than 500 credits.

You can't complete this task, because you're not signed in.

wow, you don't even have to loop through with map.values().removeIf(); Felt almost like cheating, after the last couple of tasks. You can do it the regular way too, however. Happy coding! :)

Took 10 minutes to solve and half of that was entering keys and values. As opposed to a WHOLE day for the previous two exercises lol. I hope we get more solidified on HashMaps.
