Dynamic array: Shape Area Calculation

In this problem, you will create a program that stores Circle and Rectangle objects in a parent class Shape array, calculates each shape's area, and displays the result to standard output.

Learning Objective: Store and process multiple subclass objects in parent class array

Implement Circle and Rectangle subclasses that extend the Shape class, and use polymorphism to calculate the area of each shape in a single loop.

Input

Line 1: Number of shapes n
Following lines: Shape type and dimensions

• circle [radius]
• rectangle [width] [height]

Output

Area of each shape (2 decimal places)

Area 1: [area]
Area 2: [area]
...
```java

## Example

Input:
```java
2
circle 5
rectangle 4 3
```java
Output:
```java
Area 1: 78.54
Area 2: 12.00
