Java Problem 2-4: Pennies Problem

Explanation:

The pennies problem is a classic example of exponential growth. On the first day, you start with 1 penny. On the second day, you receive 2 pennies. Each day, the amount of pennies given to you doubles from the previous day.

After 30 days of doubling the pennies given to you, you will have accumulated a total of 1,073,741,824 pennies. This is calculated by doubling the amount of pennies each day for 30 days.

It is important to use a long integer type to keep track of the total amount of pennies, as the numbers grow exponentially with each doubling. Using a regular integer type may result in overflow or incorrect calculations.
