### Problem Statement

Create a class Abacus that contains a method add that is given a String[] original and a number val and that returns a String[] showing the abacus after val has been added to the original abacus.

Both in original and in the return, the String[] will contain exactly 6 elements representing the 6 threads in order from top thread to bottom thread. Each element will contain a lowercase 'o' to represent each bead and three consecutive hyphens '-' to indicate the empty part of the thread. Each element will thus contain exactly 12 characters.

### Definition

 Class: Abacus Method: add Parameters: String[], int Returns: String[] Method signature: String[] add(String[] original, int val) (be sure your method is public)

### Constraints

-original will contain exactly 6 elements.
-Each element of original will contain exactly 12 characters, 9 lowercase 'o's and 3 consecutive '-'s.
-val will be between 0 and 999,999 inclusive.
-val added to the original abacus will result in a value that can be shown on the abacus.

### Examples

0)

 ```{"ooo---oooooo", "---ooooooooo", "---ooooooooo", "---ooooooooo", "oo---ooooooo", "---ooooooooo"}``` `5`
```Returns:
{"ooo---oooooo",
"---ooooooooo",
"---ooooooooo",
"---ooooooooo",
"o---oooooooo",
"ooooo---oooo" }```
 When we add 5 to the original, it is necessary to "carry" 1 to the next thread up. This shows the arithmetic 699979 + 5 = 699984
1)

 ```{"ooo---oooooo", "---ooooooooo", "---ooooooooo", "---ooooooooo", "oo---ooooooo", "---ooooooooo"}``` `21`
```Returns:
{"oo---ooooooo",
"ooooooooo---",
"ooooooooo---",
"ooooooooo---",
"ooooooooo---",
"ooooooooo---" }```
 This shows 699979 + 21 = 700000
2)

 ```{"ooooooooo---", "---ooooooooo", "ooooooooo---", "---ooooooooo", "oo---ooooooo", "---ooooooooo"}``` `100000`
```Returns:
{"oooooooo---o",
"---ooooooooo",
"ooooooooo---",
"---ooooooooo",
"oo---ooooooo",
"---ooooooooo" }```
3)

 ```{"o---oooooooo", "---ooooooooo", "---ooooooooo", "---ooooooooo", "---ooooooooo", "---ooooooooo" }``` `1`
```Returns:
{"---ooooooooo",
"ooooooooo---",
"ooooooooo---",
"ooooooooo---",
"ooooooooo---",
"ooooooooo---" }```
