How would you count the number of people in this room right now?

• Point at each person and count one at a time

• Ask everybody to point and count together

• Estimate the number based on the room size

What does line 1 of the pseudocode do?

• Declare and initialize a variable

• Start a loop

• Increment a counter

• Print the result

What happens if there are zero people in the room?

• The algorithm doesn't execute

• The algorithm counts the person doing the counting

• The algorithm counts the room itself

• The algorithm counts the furniture in the room

How does the optimized algorithm count people?

• Two at a time

• Three at a time

• Four at a time

• Five at a time

What is the problem with the optimized algorithm?

• It doesn't work for odd numbers of people

• It is slower than the original algorithm

• It counts the same person multiple times

• It requires a computer to execute

How does the fixed algorithm handle odd numbers of people?

• It counts the remaining person separately

• It skips counting odd numbers of people

• It pairs the remaining person with someone else

• It counts the remaining person twice

What is the term used in the video for the faulty algorithm?

Can algorithms be used to solve any problem?

• Yes, algorithms can solve any problem

• No, algorithms are limited to specific types of problems

• Only computers can use algorithms, not humans

• Algorithms are only used in computer science
