Exercise

Show each employee's first name, last name, salary, and the first name and last name of their direct manager in the same row. For employees who don't have a manager (for example the CEO), show NULL as the manager's first and last name.

Prefix the employee's columns with employee_ and the manager's with manager_, e.g.: employee_first_name.
