# Leap
|
||
|
|
|
||
|
|
Write a program that will take a year and report if it is a leap year.
|
||
|
|
|
||
|
|
The tricky thing here is that a leap year occurs:
|
||
|
|
|
||
|
|
```plain
|
||
|
|
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.
|
||
|
|
|
||
|
|
If your language provides a method in the standard library that does
|
||
|
|
this look-up, pretend it doesn't exist and implement it yourself.
|
||
|
|
|
||
|
|
## Notes

|
For a delightful, four minute explanation of the whole leap year
|

|
|
phenomenon, go watch [this youtube video][video].

To run the tests simply run the command `go test` in the exercise directory.
|
||
|
|
|
||
|
|
If the test suite contains benchmarks, you can run these with the `-bench`
|
||
|
|
flag:
|
||
|
|
|
||
|
|
go test -bench .
|
||
|
|
|
||
|
