A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours
in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Use a string formatting
expression with conversion specifiers to output the caffeine amount as floating-point numbers.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print (f' {your_value:.2f}')
Ex: If the input is:
100
the output is:
After 6 hours: 50.00 mg
After 12 hours: 25.00 mg
After 24 hours: 6.25 mg
Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg.

- The following program reads three positive integer numbers: x, y, and z entered by the user. It checks whether or not all the numbers are positive. Then, it calculates and prints the total and the average of the square of the input numbers. The result should be printed with 2 decimal points. If at least one of the input numbers is not positive, the program prints an error message.
