Write C# method IsSymmetricArray that returns true if the array is symmetric and false otherwise. You need to call this method in the Main Method .

Example:

b={ 6,3,2,3,6} is symmetric. d= {6,3,3,6} is symmetric.

e= { 1,3,3,2} is not symmetric.

In C#

Using recursion, Write a method to find the value of f(n) given:

f(0)=2, f(1)=5

f(n) = f(n-1)+2f(n-2)+4, where n is Natural number

Display the value of f(5) in the Main method.
