# Space Age
|
|
|
|
Given an age in seconds, calculate how old someone would be on:
|
|
|
|
- Earth: orbital period 365.25 Earth days, or 31557600 seconds
|
|
- Mercury: orbital period 0.2408467 Earth years
|
|
- Venus: orbital period 0.61519726 Earth years
|
|
- Mars: orbital period 1.8808158 Earth years
|
|
- Jupiter: orbital period 11.862615 Earth years
|
|
- Saturn: orbital period 29.447498 Earth years
|
|
- Uranus: orbital period 84.016846 Earth years
|
|
- Neptune: orbital period 164.79132 Earth years
|
|
|
|
So if you were told someone were 1,000,000,000 seconds old, you should
|
|
be able to say that they're 31.69 Earth-years old.

## No Stub
|
|
|
|
This may be the first Go track exercise you encounter without a stub: a
|
|
pre-existing `space_age.go` file for your solution. You may not see stubs in
|
|
the future and should begin to get comfortable with creating your own Go files
|
|
for your solutions.
|
|
|
|
One way to figure out what the function signature(s) you would need is to look
|
|
at the corresponding \*\_test.go file. It will show you what the package level
|
|
functions(s) should be that the test will use to verify the solution.
|
|
|
|
|
|
## Running the tests
|
|
|
|
To run the tests run the command `go test` from within the exercise directory.
|
|
|
|
If the test suite contains benchmarks, you can run these with the `-bench`
|
|
flag:
|
|
|
|
go test -bench .
|
|
|
|
Keep in mind that each reviewer will run benchmarks on a different machine, with
|
|
different specs, so the results from these benchmark tests may vary.
|
|

## Submitting Incomplete Solutions
|
|
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
