Introduction to Algorithm Revision Question.

Which of the following are common data types in Python?

• Integers and floats
• Strings and booleans
• Lists and tuples
• Functions and classes

What is the main benefit of using algorithms in programming?

• They help in planning and structuring code
• They replace the need for coding altogether
• They increase the number of errors in code
• They make coding more complex and difficult

What do flowcharts use to represent decision points?

• Circles
• Ovals
• Rectangles
• Diamonds

What is an algorithm?

• A sequence of instructions to perform a task
• A random set of instructions with no order
• A type of data structure in Python
• A visual representation of programming logic

What is the purpose of pseudocode?

• To outline algorithms in a human-readable format
• To write code in a strict programming language
• To create visual diagrams of algorithms
• To simplify complex programming tasks

What does abstraction help programmers do?

• Focus on essential features of a system
• Hide unnecessary details from the user
• Create complex algorithms without planning
• Increase the number of lines of code

What is decomposition in programming?

• Writing code without any structure
• Creating a single large code block
• Combining multiple problems into one
• Breaking down problems into smaller parts

Why is sequence important in programming?

• It determines the order of instruction execution
• It allows for random execution of code
• It is used to create loops in code
• It enhances the readability of the code

What is selection in programming?

• Making decisions based on conditions
• Repeating a block of code
• Defining data types in Python
• Organising code into functions

What does iteration allow programmers to do?

• Break down code into smaller functions
• Execute code in a random order
• Create static code that does not change
• Repeat a block of code multiple times
