J277 - 2.1 - Inputs, Outputs and Processes

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
