You are the last person on planet Charvis 8HD. Everyone has decided to leave because Charvis 9HD is the hipper place to live. As the last person to leave, your Captain sent you the following instructions:
"Make sure you enable the Charvis 8HD Defense System (CDS) after taking off in your spaceship."
However, you misread the instructions and activated the CDS before leaving the planet. You are now stuck on this planet. Can you figure out how to manually disable the 10 defense systems (C1 thru C10) which comprise CDS in order to safely take off?
Thankfully, Charvis 8HD does not have strong dust storms and you will not need to travel 2,000 miles in a rover.
