Algorithms

What is an algorithm?

• A process of removing unnecessary detail from a problem.

• A sequence of steps that can be followed to complete a task.

• Breaking a problem into sub-problems.

• A method of organizing data.

What does abstraction involve?

• Breaking a problem into sub-problems.

• A sequence of steps to complete a task.

• Removing unnecessary detail from a problem.

• Organizing data into a hierarchy.

What is decomposition in problem-solving?

• A sequence of steps to complete a task.

• Removing unnecessary detail from a problem.

• Breaking a problem into sub-problems, each of which achieves an identifiable task.

• Combining multiple solutions into one.

What is an algorithm?

What is the relationship between a program and an algorithm?

• A program is an implementation of an algorithm

• An algorithm is a type of program

• An algorithm is a subset of a program

What is abstraction in the context of problem-solving?

• A) Adding more details to a problem

• B) Removing unnecessary details from a problem

• C) Focusing on the color and material of objects

• D) Ignoring the problem entirely

Which of the following is an example of abstraction?

• A) Describing the exact color of a door

• B) The London Underground Map

What is decomposition in problem-solving?

• Combining multiple solutions into one

• Breaking down a problem into sub-problems

• Ignoring smaller tasks to focus on the main problem

• Solving problems without any structure

What is the goal of decomposing a problem into sub-problems?

• To make the problem more complex

• To achieve a single identifiable task

• To avoid solving the problem

• To create more problems
