Bubble sort in c#

Bubble sort is the simplest sorting algorithm. As per name the sorting will be done sequentially by iterating down an array to be sorted from the first element to the last, comparing each pair of elements and switching their positions if necessary. This process is repeated as many times as necessary, until the array is sorted.

Inversion of Control and how it's different from the dependency inversion principle?

Most of the people mix the DIP, IOC and DI together but, Inversion of Control is part of a dependency inversion principle.  As per  dependency inversion principle high level module should not be dependent on lower level modules so Inversion of Control is a way to solve this problem.

Dependency inversion Principle

Dependency Inversion principle is a part of SOLID principle. It was given by Bob Martin, who is founder of SOLID principles.

Bob's Definition

  • High level module should not be dependent on lower level modules. Both should dependent on abstraction.
  • Abstraction should not dependent on details. Details should be dependent on abstraction.
