Algorithm test
===

Nathan's version of BM search.

Given the skeleton in place in the code, and its type annotations, fill in a simplified version of the BM search algorithm.

It only returns the first occurrence of the pattern, and it only uses the "bad character" criteria from the algorithm.
The lookup table is a sparse dictionary instead of a full alphabet like the C version.


### Usage

```bash
$ python3 -m pip install pipenv

# Use virtualenv
$ PIPENV_VENV_IN_PROJECT=true pipenv shell

$ pipenv install --dev
```

- Unittest

```bash
$ pipenv run unittest
```
