Welcome to Leap on Exercism's Go Track.
If you need help running the tests or submitting your code, check out HELP.md.
Given a year, report if it is a leap year.
The tricky thing here is that a leap year in the Gregorian calendar occurs:
on every year that is evenly divisible by 4
except every year that is evenly divisible by 100
unless the year is also evenly divisible by 400
For example, 1997 is not a leap year, but 1996 is. 1900 is not a leap year, but 2000 is.
Though our exercise adopts some very simple rules, there is more to learn!
For a delightful, four minute explanation of the whole leap year phenomenon, go watch this youtube video.
You will see a cases_test.go file in this exercise. This holds the test
cases used in the leap_test.go. You can mostly ignore this file.
However, if you are interested... we sometimes generate the test data from a
cross language repository. In that repo
exercises may have a .json file that
contains common test data. Some of our local exercises have an
intermediary program that takes the problem specification
JSON and turns in into Go structs that are fed into the <exercise>_test.go
file. The Go specific transformation of that data lives in the cases_test.go file.
