# 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`: ``` S E N D M O R E + ----------- M O N E Y ``` Replacing these with valid numbers gives: ``` 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. ## Running the tests To run the tests, run the command `busted .` from within the exercise directory. ## Further information For more detailed information about the Lua track, including how to get help if you're having trouble, please visit the exercism.io [Lua language page](http://exercism.io/languages/lua/about). ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
