Write a program that calculates the moment when someone has lived for 10^9 seconds.
A gigasecond is 10^9 (1,000,000,000) seconds.
My solution (with a lot of digging around Google..)
First, define Gigasecond as a Ruby constant since that shouldn’t ever change.
Then, to figure out the moment someone has lived for that long, take their birthdate and add the defined constant to it. (No need to do any conversions as the date/time format for the result is no different from format of the given birthdate.)
Here are test cases it should pass.
Notes: Encountered .from for the first time in this problem. Also learned to define Ruby constants once again.
