Top Down Design and Decomposition in Karel

The video introduces top down design and decomposition, explaining how to break down large problems into smaller, manageable parts. Using the example of making a movie, the concept of decomposition is illustrated. The video then applies these principles to solve a problem in Karel, a programming environment. Functions are used to break down the task of navigating hurdles, demonstrating how top down design can simplify complex problems and make code more readable and efficient.

What is one of the main reasons for using functions in programming?

• To make the code run faster

• To make the code harder to read

• To break down the program into smaller parts

• To increase the complexity of the code

What is the first step in top down design when faced with a big problem?

• Ask someone else to solve it

• Ignore the problem

• Break it down into smaller problems

• Solve the problem immediately

In the movie example, what is one of the big problems that needs to be broken down?

• Watching the movie

• Promoting the movie

• Writing the script

• Choosing the movie title

What is the initial position of Karel in the Hurdle Karel problem?

• Bottom world, facing west

• Bottom world, facing east

• Top world, facing west

• Top world, facing east

What is the first function Karel needs to perform in the Hurdle Karel problem?

• Jump over the hurdle

• Run to the hurdle

• Turn left

• Move to the finish

How many times does Karel need to move to run to the hurdle?

• Two times

• One time

• Four times

• Three times

What is the sequence of actions Karel performs to jump a hurdle?

• Turn right, move, turn left

• Turn right, move, turn right

• Turn left, move, turn right

• Move, turn left, move

How does Karel turn right in the program?

• By turning left three times

• By turning right once

• By turning left twice

• By moving forward and turning left

What is the final function Karel performs to complete the Hurdle Karel problem?

• Run to the finish

• Jump the last hurdle

• Turn left

• Move to the start

What is the main benefit of using functions to solve the Hurdle Karel problem?

• To make Karel move slower

• To make the code longer

• To avoid repeated code

• To confuse the programmer
