TED-Ed: The Train Heist | Think Like A Coder, Ep 4 | Alex Rosenthal

The video tutorial outlines a plan to steal an artifact called the node of power from a fortified train. The train's movement is controlled by a complex unloading procedure, and a robot named Hedge must press a button to lower a forcefield at the right moment. The solution involves programming a variable to track the train's position. The plan is executed successfully, and the artifact reveals a vision of the past, leading to the next mission.

What is the primary function of the node of power in the train?

• To power the train's engine

• To provide supplies to settlements

• To maintain the train's forcefield

• To control the train's navigation

How can Hedge determine the train's position to lower the forcefield?

• By using a GPS system

• By analyzing the unloading procedure

• By looking out the window

• By communicating with Ethic

What is the initial position of the train under the crane?

• Car 15

• Car 0

• Car 5

• Car 10

What happens when the train moves one car to the right?

• The position variable increases by 1

• The position variable decreases by 1

• The position variable remains the same

• The position variable doubles

What is the significance of the variable hitting zero in the problem-solving approach?

• It indicates the train has stopped

• It means the train is off track

• It shows the train is at full speed

• It signals Hedge to press the button

What role does Ethic play in the heist?

• She programs Hedge

• She operates the crane

• She analyzes the train's position

• She distracts the guards

What is revealed about Ethic's past after the heist?

• She was a government official

• She discovered the node of power

• She created her first robot at the console

• She was a former train engineer
