### Frequently Asked Questions About KS3 Introduction to Algorithms

#### What is an algorithm?

An algorithm is a set of instructions for solving a problem or performing a task. It is a step-by-step procedure for achieving a desired outcome.

#### What is the difference between a linear and a non-linear algorithm?

A linear algorithm is one in which the running time increases proportionally with the size of the input, while a non-linear algorithm is one in which the running time increases at a rate greater than proportionally with the size of the input.

#### What is the space complexity of an algorithm?

The space complexity of an algorithm is a measure of the amount of memory used by the algorithm as a function of the size of the input. It is also usually expressed using big O notation.

#### What is the purpose of the analysis of algorithms?

The analysis of algorithms is the process of determining the time and space complexity of an algorithm, and is used to compare the efficiency of different algorithms for a given problem. It allows us to determine the best algorithm for a particular task by comparing their performance characteristics.

#### What is the time complexity of an algorithm?

The time complexity of an algorithm is a measure of the amount of time it takes for the algorithm to run as a function of the size of the input. It is usually expressed using big O notation.
