# 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].

## Rust Installation
|
||
|
|
|
||
|
|
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||
|
|
resources.
|
||
|
|
|
||
|
|
## Writing the Code
|
||
|
|
|
||
|
|
Execute the tests with:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ cargo test
|
||
|
|
```
|
||
|
|
|
||
|
|
All but the first test have been ignored. After you get the first test to
|
||
|
|
pass, remove the ignore flag (`#[ignore]`) from the next test and get the tests
|
||
|
|
to pass again. The test file is located in the `tests` directory. You can
|
||
|
|
also remove the ignore flag from all the tests to get them to run all at once
|
||
|
|
if you wish.
|
||
|
|
|
||
|
|
Make sure to read the [Crates and Modules](crates-and-modules) chapter if you
|
||
|
|
haven't already, it will help you with organizing your files.
