# Series
|
||
|
|
|
||
|
|
Given a string of digits, output all the contiguous substrings of length `n` in
|
||
|
|
that string.
|
||
|
|
|
||
|
|
For example, the string "49142" has the following 3-digit series:
|
||
|
|
|
||
|
|
- 491
|
||
|
|
- 914
|
||
|
|
- 142
|
||
|
|
|
||
|
|
And the following 4-digit series:
|
||
|
|
|
||
|
|
- 4914
|
||
|
|
- 9142
|
||
|
|
|
||
|
|
And if you ask for a 6-digit series from a 5-digit string, you deserve
|
||
|
|
whatever you get.
|
||
|
|
|
||
|
|
Note that these series are only required to occupy *adjacent positions*
|
||
|
|
in the input; the digits need not be *numerically consecutive*.

## Elm Installation
|
||
|
|
|
||
|
|
Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
|
||
|
|
installation and learning resources.
|
||
|
|
|
||
|
|
## Writing the Code
|
||
|
|
|
||
|
|
The first time you start an exercise, you'll need to ensure you have the
|
||
|
|
appropriate dependencies installed.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm install
|
||
|
|
```
|
||
|
|
|
||
|
|
Execute the tests with:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm test
|
||
|
|
```
|
||
|
|
|
||
|
|
Automatically run tests again when you save changes:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm run watch
|
||
|
|
```
|
||
|
|
|
||
|
|
As you work your way through the test suite, be sure to remove the `skip <|`
|
||
|
|
calls from each test until you get them all passing!
