#### Summing Even Numbers in an Array

This technical problem deals with writing a function that returns the sum of the even numbers in an array. An example input and output are provided.

#### Problem

```Given an array of integers, write a function that returns the sum of the even numbers in the array.
Example input: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Example output: 30```

#### Solution

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

function sumEven(arr) {
let sum = 0;
for (let i = 0; i < arr.length; i++) {
if (arr[i] % 2 === 0) {
sum += arr[i];
}
}
return sum;
}

// Explanation:

// This solution is optimal because it uses a for loop to iterate through the array and check if each element is even. If it is, it adds it to the sum. This solution is optimal because it only iterates through the array once, and it doesn't use any extra space.```

A.I. Evaluation of the Solution

This is a great solution! It is very efficient and only iterates through the array once.
