Use Default Constructor Values
Learn to rely on default __init__ parameter values when constructing objects.

Problem statement
Implement rectangle_area(width=None, height=None) that:
- Uses the Rectangle class below. Rectangle's __init__ has default width and height of 1.
- If width or height is None, use the class defaults for those dimensions.
- Return the area (width * height) as an integer.
This tests using classes with default constructor parameters and conditional instantiation.
Task
Instantiate a class that provides default constructor values and compute a result using those defaults when needed.
Examples
Input format
Two parameters: width (int or None), height (int or None). Use None to indicate the class default should be used for that dimension.
Output format
An integer representing the area.
Constraints
width and height are integers >= 0 or None. Use the Rectangle defaults when None is passed.
Samples
Sample 1
Input
rectangle_area(None, 4)
Output
4
Width uses default 1, height 4 => area 4.
