@vibranttester Design pattern is a general repeatable solution to a
commonly occurring problem in software design. 5

@vibranttester Intent of the pattern briefly describes both the problem
and the solution. What does Structure of classes shows each part of the pattern and how they are related Intent Motivation Structure Motivation further explains the problem and the solution the pattern makes possible Code Design pattern consist of? Code in any of the popular programming language makes it easier to grasp the idea behind the pattern 6
