- Max Array Sum

# Max Array Sum

# Max Array Sum

Given an array of integers, find the subset of non-adjacent elements with the maximum sum. Calculate the sum of that subset.

For example, given an array we have the following possible subsets:

```
Subset Sum
[-2, 3, 5] 6
[-2, 3] 1
[-2, -4] -6
[-2, 5] 3
[1, -4] -3
[1, 5] 6
[3, 5] 8
```

Our maximum subset sum is .

**Function Description**

Complete the function in the editor below. It should return an integer representing the maximum subset sum for the given array.

maxSubsetSum has the following parameter(s):

*arr*: an array of integers

**Input Format**

The first line contains an integer, .

The second line contains space-separated integers .

**Constraints**

**Output Format**

Return the maximum sum described in the statement.
