# Sublist

Given two lists determine if the first list is contained within the second
list, if the second list is contained within the first list, if both lists are
contained within each other or if none of these are true.

Specifically, a list A is a sublist of list B if by dropping 0 or more elements
from the front of B and 0 or more elements from the back of B you get a list
that's completely equal to A.

Examples:

 * A = [1, 2, 3], B = [1, 2, 3, 4, 5], A is a sublist of B
 * A = [3, 4, 5], B = [1, 2, 3, 4, 5], A is a sublist of B
 * A = [3, 4], B = [1, 2, 3, 4, 5], A is a sublist of B
 * A = [1, 2, 3], B = [1, 2, 3], A is equal to B
 * A = [1, 2, 3, 4, 5], B = [2, 3, 4], A is a superlist of B
 * A = [1, 2, 4], B = [1, 2, 3, 4, 5], A is not a superlist of, sublist of or equal to B

## Hints

To complete this exercise, you need to implement the `sublist` function.



## Getting Started

For installation and learning resources, refer to the
[exercism help page](http://exercism.io/languages/haskell).

## Running the tests

To run the test suite, execute the following command:

```bash
stack test
```

#### If you get an error message like this...

```
No .cabal file found in directory
```

You are probably running an old stack version and need
to upgrade it.

#### Otherwise, if you get an error message like this...

```
No compiler found, expected minor version match with...
Try running "stack setup" to install the correct GHC...
```

Just do as it says and it will download and install
the correct compiler version:

```bash
stack setup
```

## Running *GHCi*

If you want to play with your solution in GHCi, just run the command:

```bash
stack ghci
```
