Algorithms
In mathematics and computer science, an algorithm is a finite sequence of
well-defined, computer-implementable instructions, typically to
solve a class of specific problems or to perform a computation.
What is an example of an algorithm?
One of the most obvious examples of an algorithm is a recipe. It's a finite list of instructions used to perform a task. For example, if you were to follow the algorithm to create brownies from a box mix, you would follow the three to five step process written on the back of the box.
What are the characteristics of algorithm?
Algorithm and its characteristics
Finiteness. An algorithm must always terminate after a finite number of steps.
Definiteness. Each step of an algorithm must be precisely defined; the actions to be carried out must be rigorously and unambiguously specified for each case.

Effectiveness.
What are the 5 properties of algorithm?
An algorithm must have five properties:
Input specified.
Output specified.

What is Big O function?
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. ... In computer science, big O notation is used to classify algorithms according to how their run time or space requirements grow as the input size grows.
