Question

Did you know that there are more bacteria cells in your body than cells that make up your body? Weird!

A bacteria culture starts with 500 bacteria and doubles in size every hour.
Which means, after 1 hour the number of bacteria is 1000, after 2 hours - 2000, and so on.

Let’s calculate and output the number of bacteria that will be in the culture after 24 hours.

Answer 1

500*2**24

Answer 2

500 << 24
