Python Food Ordering Algorithm Quiz

Which data structure is most suitable for storing a restaurant's menu in a food ordering system?

• List

• Dictionary

• Set

• Tuple

How can you ensure a user inputs a valid menu item number when ordering food?

• Use a while loop that continues until a valid input is received

• Use a for loop with a range of valid numbers

• Use an if statement to check the input once

• Use a try-except block to catch a ValueError

What is the purpose of error handling in a food ordering algorithm?

• To speed up the ordering process

• To prevent the program from crashing due to unexpected inputs

• To make the code shorter and more readable

• To add more features to the food ordering system

Which Python keyword is used to handle exceptions?

• handle

• error

• try

• except

In the context of algorithm design for food ordering, what is the first step in developing an efficient algorithm?

• Choosing the right data structures

• Writing pseudocode

• Identifying the problem to be solved

• Optimizing the code for speed

Which of the following is an optimization technique that can be used in a food ordering algorithm?

• Using global variables

• Minimizing the use of loops

• Caching frequently accessed data

• Increasing the number of conditional statements

How can you improve the time complexity of a search operation in a food ordering system?

• By using a linear search algorithm

• By using a binary search algorithm on a sorted list

• By searching each item in a dictionary

• By increasing the number of items in the menu

Which Python function is used to get input from the user?

• print()

• input()

• get()

• read()

What is the best way to validate user input in a Python food ordering system?

• Ask the user to input their choice again if the first input is invalid

• Use a regular expression to validate the input format

• Immediately exit the program if the input is invalid

• Assume all input is valid and proceed without validation

Which of the following is NOT a common use case for using tuples in a food ordering system?

• Storing the names of the dishes

• Storing the price of each dish as a constant value

• Modifying the menu items frequently

• Storing the order in which dishes should be prepared
