Caffeine has a half-life of about 6 hours in humans. (A half-life is the amount of time it takes for a substance to fall to half its original value.) Given caffeine_amount as input, output the caffeine level after 6 hours (caffeine_amount/2), 12 hours (caffeine_amount/4), and 24 hours (caffeine_amount/16).

Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))

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
