✏️ Explanatory Question
1. Define a class method getCircleCount inside Circle which returns the number of circle objects created. Hint: Use classmethod decorator.
2. Try accessing the class method using an object and the class.
3. To test the number of circles created and the area of each circle, provide the radius of each circle in the input.
4. Output the total count of circles.
5. Check the main/tail section for output handling (read-only).
6. Use the Test against custom input box to output the result for debugging.
7. Provide float values separated by comma (refer test case samples) to display the output/error. The outputs should be split into 2 lines:
• The 1st output should return a key-value pair of the circle number and its corresponding area.
• The 2nd output should return the number of circles created or the number of inputs provided.
