Compose Comparators

Work with records inside Solution: - record Employee(String name, String dept, int salary) - static List<String> topPaidByDept(List<Employee> staff, int n): group employees by dept, sort each group by salary DESCENDING (ties by name ASCENDING), and return dept + ":" + name for the top n of each group, with depts in alphabetical order. Use Comparator.comparing/thenComparing — no anonymous classes.
