#### Adding Rows of a 2D Array

You are given a two dimensional array containing arrays of integers as an argument. Find the largest integer that can be obtained by summing all integers along any row or column.

Inner arrays may or may not contain equal number elements in each.

### Requirements

- Must return an integer

#### Example #1

```
solve([
[1, 2, 5, 1, 5, 1],
[0, 4, 5, 7, 7, 3],
[1, 6, 7, 1, 7, 8]
])
> 30
```

*Summing up all integers in row three 1+6,+7+1+7+8 gives us the largest sum, so we return 30.*

#### Example #2

```
solve([
[1, 2, 2, 1, 5, 4],
[0, 1, 1, 2, 1, 9],
[1, 2, 2, 1, 3, 8]
])
> 21
```

*Summing up all integers in column six 4+9+8 gives us the largest sum, so we return 21.*
