Problem Statement

The smallest digit in an integer is defined to be the digit closest to 0 out of the possible 0 - 9.

Create a class Digits that contains the method sumDigits, which takes in the parameter int[], numbers, and returns the sum of the smallest digit from all the numbers.

Definition

Class:: Digits
Method:: sumDigits
Parameters:: int[]
Returns:: int
Method signature:: int sumDigits(int[] numbers)
(be sure your method is public)

Notes

the integer 0 is seen as having a smallest digit of 0
no integers will have leading 0's (99 will never be seen as 099)

Constraints

numbers has between 1 and 20 elements, inclusive
Each element of numbers is between -1000 and 1000, inclusive
All integers are considered to be base 10, and will only have digits 0 - 9

Examples

```
{987}
```
```
Returns: 7
```
7 is the smallest digit out of the possible digits 7, 8, and 9.
```
{987, -990}
```
```
Returns: 7
```
7 is the smallest digit of 987, and 0 is the smallest digit from -990. 7 + 0 = 7
```
{48, -88, 46, -45, 22}
```
```
Returns: 22
```
```
{675,-946,999,18}
```
```
Returns: 19
```
