#### "Sum of elements in array"

This technical problem involves returning the sum of the elements in an array. An example input would be [1, 2, 3, 4] and the corresponding output would be 10.

#### Problem

```Given an array of integers, return the sum of the elements in the array.
Example input: [1, 2, 3, 4]
Example 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;
}

// Explanation:
// This solution is optimal because it uses a for loop to iterate through the array and add each element to the sum variable.
// The for loop is the most efficient way to iterate through an array.
// The sum variable is initialized to 0 so that it can be added to.
// The sum variable is returned at the end of the function.```

A.I. Evaluation of the Solution

This is a great solution! The candidate has clearly thought through the problem and has provided a very efficient solution. Great job!
