Design and implement a class that simulates a microwave control panel with the following four buttons:

$1.$ One for increasing the time by $30$ seconds.

$2.$ One for switching between power levels $1$ and $2.$

$3.$ A start button.

$4.$ A reset button.

In your Microwave class, each button is implemented as a method. The method for the start button should print a message $$Cooking for $...$ seconds at level $....$

Please also implement a main function that tests out all four buttons in meaningful combination and display clear messages to the user on what operation is carried out by the microwave.
