1 - Create a class with the following functions :-
    1 - Function to return the Area of a circle
    2 - Function to return the circumference of a circle
    3 - Function to return the Area of a Square
    4 - Function to return the circumference of a square
    5 - Function to return the Area of a rectangle
    6 - Function to return the circumference of rectangle

2 - Create a class with the following functions :-
    1 - Function that takes two numbers X & Y and return XY

       public static int Power(int X, int Y)
       {          Your Code         }   
    
    2 - Function that takes a number and return True if the number is Even 
        and false if the number is odd

        public static bool IsEven(int number)
        {          Your Code         }
