Brain Teaser: Update the above code such that that unit tests pass. Do not update the content of the unit tests (however you are allowed to switch off of xUnit if you like).

Personal notes on presenting and streaming.

Before starting

• Turn off un-needed software. Especially things with notifications: Slack, Skype, Teams, etc.
• Turn on Focus Assist
• When sharing your desktop, consider sharing a secondary screen rather than the primary screen. Many apps will post notifications to the primary screen so this will help cut down on accidently sharing out notifications.
• Hide desktop icons
• Consider resolution/DPI. Remember that for streaming, people watching may be on lower resolutions; don't stream above 1080p.
• Hide task bar. Either set auto hide, or simply crop the shared section of your screen to omit it.
• Consider if desktop background is appropriate.
