# Alphametics

Write a function to solve alphametics puzzles.

[Alphametics](https://en.wikipedia.org/wiki/Alphametics) is a puzzle where
letters in words are replaced with numbers.

For example `SEND + MORE = MONEY`:

```text
  S E N D
  M O R E +
-----------
M O N E Y
```

Replacing these with valid numbers gives:

```text
  9 5 6 7
  1 0 8 5 +
-----------
1 0 6 5 2
```

This is correct because every letter is replaced by a different number and the
words, translated into numbers, then make a valid sum.

Each letter must represent a different digit, and the leading digit of
a multi-digit number must not be zero.

Write a function to solve alphametics puzzles.

## Setup

Go through the setup instructions for JavaScript to install the
 necessary dependencies:

http://exercism.io/languages/javascript/installation

## Running the test suite

The provided test suite uses [Jasmine](https://jasmine.github.io/).
You can install it by opening a terminal window and running the
following command:

```sh
npm install -g jasmine
```

Run the test suite from the exercise directory with:

```sh
jasmine alphametics.spec.js
```

In many test suites all but the first test have been marked "pending".
Once you get a test passing, activate the next one by changing `xit` to `it`.

## Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
