# Gator And Ducks

Simple+

Suppose there are `ducks` floating on the pond in a circle. The pond is also home for alligator with a fondness for ducks. Beginning at a particular position (duck number 1) the alligator counts clockwise around the circle and eats every `step`-th duck (the circle closing as ducks are eaten).

For example, when `ducks = 8` and `step = 4`, the following diagram shows duck number outside and consumption order inside:

The first duck is fifth on the menu, the second is forth, etc. The sequence `5, 4, 6, 1, 3, 8, 7, 2` of orders of consumption completely describes alligator's menu.

Write a script which returns the orders of consumption of the ducks given `ducks, step`.

Input: Two integers (int).

Output: List of integers.

Examples:

```assert gator(8, 4) == [5, 4, 6, 1, 3, 8, 7, 2]
assert gator(7, 11) == [7, 2, 3, 1, 5, 6, 4]
assert gator(3, 1) == [1, 2, 3]
```

Precondition:

• ducks, step > 0

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

`pip3 install checkio_client`

`checkio --domain=py config --key=`

Sync solutions into your local folder

`checkio sync`

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

`checkio serv -d`

Alternatevly, you can install Chrome extension or FF addon

`checkio install-plugin`
`checkio install-plugin --ff`
`checkio install-plugin --chromium`

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
