What is an Algorithm

Algorithm refers to a set of rules and instructions that defines how a task is to be executed upon in order to get the expected results. Algorithm defines the output based on set of rules that applies to input data. Therefore, it is important to define input and output before setting the rules and instructions for the algorithm to work. In cases where the input is not defined properly, the algorithm sometime delivers inconsistent output results.

 

Let’s take example of a smartphone to understand how algorithm works:

 

In auto brightness mode, the smartphone’s display adjusts the screen brightness based on ambient light
