#### Summing the Elements of an Array

This technical problem involves writing a function that takes an array of integers as input and returns the sum of all the elements in the array.

#### Problem

```Given an array of integers, write a function that returns the sum of the elements in the array.
Input:
[1, 2, 3, 4]
Output:
10```

#### Solution

This solution is in JavaScript. Our A.I. can create solutions in multiple languages.
```// Solution:

function sum(arr) {
let sum = 0;
for (let i = 0; i < arr.length; i++) {
sum += arr[i];
}
return sum;
}

// This solution is optimal because it uses a for loop to iterate through the array and add each element to the sum variable.
// This solution is O(n) because the time it takes to run is directly proportional to the size of the input.```

A.I. Evaluation of the Solution

This solution is correct and demonstrates a good understanding of how to solve the problem. The approach is straightforward and the code is clean and easy to read.
