## Task 1
------

The program starts with a stored username and password:

> username: Samantha  password: Java<3

When signing in, prompt the user to enter their username and password.

## Task 2

Set up a loop that keeps running while the username OR password is incorrect.

## Visualizing the Runtime

After you solve this workbook, I still recommend watching the video solution on Udemy.

It will show you how to visualize the runtime using Visual Studio Code.
