TED-Ed: The Gauntlet | Think Like A Coder, Ep 8 | Alex Rosenthal

Ethic embarks on a quest to collect powerful artifacts, facing challenges in a maze of paths. The concept of recursion is introduced as a solution to navigate the maze, allowing Hedge to find the correct path to the artifact. The video explains recursion, its application, and how it helps solve complex problems. In the end, Ethic and her allies use the information gathered to escape from the pursuing robots.

What is the significance of the node of memory in the story?

• It is the last artifact Ethic needs.

• It is a communication device.

• It powers the robots.

• It controls the river of energy.

What unique ability does Hedge possess to help navigate the maze?

• He can teleport to the artifact.

• He can create smaller versions of himself.

• He can destroy the maze walls.

• He can fly over the maze.

How does recursion differ from loops in programming?

• Recursion is used only for mathematical calculations.

• Loops can solve more complex problems than recursion.

• Recursion involves repeating actions until a base case is reached.

• Recursion is faster than loops.

What is the base case in the context of Hedge's pathfinding?

• When Hedge encounters a dead end.

• When Hedge creates a new copy.

• When Hedge starts the journey.

• When Hedge reaches the artifact.

What is the role of the Pathfinder function in Hedge's strategy?

• To map the entire maze using recursion.

• To create new paths in the maze.

• To communicate with Ethic and Lema.

• To destroy incorrect paths.

How do Hedge's copies communicate the correct path back to the original?

• By sending a signal through the maze walls.

• By radioing the path they took to their parent.

• By marking the path with symbols.

• By returning to the starting point.

What happens after Hedge's radio crackles to life with directions?

• The artifact is destroyed.

• Ethic, Lema, and Hedge escape on the conveyor.

• The maze collapses.

• Ethic and Lema are captured by the bots.
