What is an algorithm?

• Error in a program

• Image of code

• Step-by-step method to solve a problem

• Type of programming error

Can one problem be solved in different ways using different algorithms?

• No

• Yes

• Only in mathematics

• Only in games

What do we call different methods to solve the same task?

• Bugs

• Function

• Algorithm

• Error

Which problem can have multiple solutions?

• Sorting numbers

• Typing a word

• Printing a message

• Declaring a variable

Why do we use different algorithms to solve the same problem?

• For fun

• To confuse the computer

• Because some are faster or simpler

• To make mistakes

Which of the following is an example of solving a problem in a different way?

• Adding using a calculator or your fingers

• Typing faster

• Writing your name

• Charging your phone

Which of the following best describes an algorithm?

• A collection of images

• A step-by-step process

• Program errors

• Shortcut keys

What is one benefit of comparing different algorithms?

• Making your code longer

• Seeing which one crashes first

• Choosing the most efficient solution

• Avoiding learning new code

What does it mean if an algorithm is more efficient?

• Harder to understand

• Uses fewer steps

• Crashes faster

• Takes more time

Which one shows different ways to sort numbers?

• Bubble sort and selection sort

• Input and output

• Loop and string

• Print and print
