What is an algorithm?
A random set of steps to solve a problem
A repeatable set of steps that can be used to perform a task and solve part of a problem
A single step to solve a problem
A vague idea of how to solve a problem
What is the first step in designing an algorithm?
Consider the process
Consider the output
Consider the input
Consider the programming language
Which of the following is NOT a tool used to represent an algorithm?
Pseudocode
Flowchart
Structured English
Spreadsheet
What is the term used to describe the mindset needed to design an algorithm?
Logical thinking
Algorithmic thinking
Creative thinking
Critical thinking
Why is it important for an algorithm to be well-defined?
So it can be vague and open to interpretation
So it can be understood and replicated by anyone
So it can be used only by the original designer
So it can be written in any programming language
What should you consider when thinking about the input for an algorithm?
The colour of the input
The data type and source of the input
The size of the input
The speed of the input
What is the purpose of using pseudocode in algorithm design?
To write code in a specific programming language
To make algorithms easy to interpret without needing a specific programming language
To create a visual representation of the algorithm
To test the algorithm's efficiency
What is the importance of understanding the output format in algorithm design?
To ensure the output is colourful
To define the end point of the solution
To make the output complex
To ignore the input data
Which of the following is a core concept used in designing the process of an algorithm?
Colour
Sequence
Size
Speed
What is the benefit of well-documented program code?
It makes the code harder to understand
It helps those unfamiliar with the language to understand the algorithm
It hides the algorithm's purpose
It makes the code run faster
