Title: Fix not intended change of argument

## Problem

`mlcs(arr)` deletes 1st member of `arr`

## Example

```coffee
arr = ["123", "12345", "123456"]
mlcs = require "mlcs"
console.log arr # => ["123", "12345", "123456"]
mlcs arr # => '123'
console.log arr # => ["12345", "123456"] "123" is deleted !!
```
This PR is for fixing this problem :smiley:
