Add a method named union to the Rectangle class. Use your Rectangle class solution from the previous exercises as a starting point to solve this exercise.

Suppose a class named Rectangle has already been created that has the following members:

member name type description
Rectangle(x, y, w, h) constructor Initializes a new rectangle whose top-left corner is specified by the given (x, y) coordinates and with the given width and height, w by h. Raises a ValueError on a negative width or height.
ba._x,
ba._y,
ba._width,
ba._height 		data attributes private attributes storing rectangle coordinates
ba.x,
ba.y,
ba.width,
ba.height 		property the rectangle location and dimensions (read-only)
str(r) method returns a string representation of the rectangle, such as "Rectangle[x=1,y=2,width=3,height=4]".

Add a method named union to your class. Your method should accept another rectangle as a parameter, and return a new rectangle that represents the area occupied by the tightest bounding box that contains both the current rectangle (self) and the given other rectangle.

Member function: Write a member function that will become part of an existing class. You do not need to write the complete class.
