In a recursive method with C#, we need two properties:
1) The base case (or cases) is a terminating scenario. It will instruct the recursion to stop, and the method return back to its orginal call. The base case does not use recursion to produce an answer, it is rather a simple if statement.

2) A recursive method, of course, includes a “recursive step” , statements that should be executed repetitively, but with every iteration using a value that it either more or less than the previous iteration. This value change should reduce the successive cases and work towards achieving the base case. The repetition is effected by the method calling itself.
