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.
