# Pythagorean Triplet
A Pythagorean triplet is a set of three natural numbers, {a, b, c}, for
which,
```text
a**2 + b**2 = c**2
```
For example,
```text
3**2 + 4**2 = 9 + 16 = 25 = 5**2.
```
There exists exactly one Pythagorean triplet for which a + b + c = 1000.
Find the product a * b * c.
## 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 [Modules](https://doc.rust-lang.org/book/second-edition/ch07-00-modules.html) chapter if you
haven't already, it will help you with organizing your files.
