Exercise $4\mathrm{.}1$

The Tiny Retailer keeps records of the skills each employee has. An employee has a name and a list of all the skills they possess. When an employee acquires a new skill, it should be added to their skill list.

To demonstrate the Employee class, create a class called EmployeeTest with the main$()$ method. The main$()$ method initializes a new employee with two skills already in the list. Then, it displays a menu with the following options:

$$

$1.$ Add a skill.

$2.$ Drop a skill.

$3.$ Find the position of a skill.

$4.$ Display all skills.

$5.$ Sort skills.

$6.$ Exit.

$$

Include the code for each task. The menu will be displayed after each task until the user selects 'exit'.
