# 241. Different Ways to Add Parentheses

Given a string of numbers and operators, return all possible results from computing all the different possible ways to group numbers and operators. The valid operators are `+`, `-` and `*`.

Example 1:

```Input: `"2-1-1"`
Output: `[0, 2]`
Explanation:
((2-1)-1) = 0
(2-(1-1)) = 2```

Example 2:

```Input: `"2*3-4*5"`
Output: `[-34, -14, -10, -10, 10]`
Explanation:
(2*(3-(4*5))) = -34
((2*3)-(4*5)) = -14
((2*(3-4))*5) = -10
(2*((3-4)*5)) = -10
(((2*3)-4)*5) = 10
```
