# 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.
