Unit 1 - 5.Linear search algorithms

Open Ended

Why is it important to understand how search algorithms work in our daily lives?

Multiple Choice

Which of these is an example of using a search algorithm in everyday life?

• Writing an essay without references

• Turning off your smartphone

• Playing a song on the radio without choosing it

• Browsing for gift ideas on an online shop

Multiple Choice

A linear search compares each value in a list one at a time until it finds a match.

• True

• False

Multiple Choice

What does a linear search do?

• a) It searches for a value by dividing the list into halves

• b) It checks each item in a list one by one until it finds a match

• c) It only works if the list is already sorted

• d) It jumps directly to the middle of the list

Multiple Choice

A linear search is also called a serial search.

• True

• False

Fill in the Blanks

A linear search algorithm checks each item in a

until it finds a match or reaches the end.

Multiple Choice

Which of the following is an example of a linear search in real life?

• Looking up a friend's name in a contact list one by one

• Using a search engine to find a website instantly

• Sorting a list of numbers from smallest to largest

• Encrypting a message for privacy

Multiple Choice

What does a linear search do?

• a) It searches for a value by dividing the list into halves

• b) It only works if the list is already sorted

• c) It checks each item in a list one by one until it finds a match

• d) It jumps directly to the middle of the list

Multiple Choice

Based on the pseudocode provided, what would happen if the user's film choice is not in the list?

• The program would display an error message.

• The program would keep looping forever.

• The program would finish without displaying a film name.

• The program would restart from the beginning.

Multiple Choice

A linear search is also called a serial search.

• True

• False

Multiple Choice

Why is pseudocode useful when designing algorithms?

• a) It ensures the program will always run faster

• b) It can be directly executed by the computer

• c) It helps us write logical steps that can later be translated into code

• d) It eliminates the need to write Python code

Multiple Choice

In the Python linear search example, the computer keeps guessing until it finds the correct answer.

• a) True

• b) False

Multiple Select

Which of the following are important points to consider when creating a simple guessing game using Python, according to the lesson?

• The game should use positive numbers only

• The game should ask if its guess is correct

• The game should use decimal points for age

• The game should guess again if it is wrong

Multiple Choice

Which of the following is an important point for the guessing game?

• a) The game must use decimal points for age

• b) The game needs to ask if its guess is correct

• c) The game must include lots of help text

• d) The game should collect personal information

Multiple Choice

In the guessing game, using decimal points for the age is required.

• True

• False

Multiple Choice

In the Python linear search code, what does the line choice = choice + 1 do?

• a) It resets the guess back to 0

• b) It increases the guess number by 1

• c) It asks the user for input

• d) It ends the program

Multiple Choice

The program begins by asking “Are you 10?”

• True

• False
