#### Summing Even Numbers in an Array

This technical problem deals with creating a function that will take in an array of integers and return the sum of all the even numbers in the array.

#### Problem

```Create a function that will take in an array of integers and return the sum of all the even numbers in the array.
Input: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Output: 30```

#### Solution

This solution is in SQL. Our A.I. can create solutions in multiple languages.
```SELECT SUM(CASE WHEN number % 2 = 0 THEN number ELSE 0 END) AS even_sum
FROM numbers;

/*

The above solution is optimal because it uses a CASE statement to check if the number is even and then returns the number if it is even and 0 if it is not.
The SUM function then adds up all the numbers in the column.

*/```

A.I. Evaluation of the Solution

The candidate's solution is correct and demonstrates a level of completeness. The candidate's approach is also optimal, making use of a CASE statement to check if the number is even and then returning the number if it is even and 0 if it is not. The SUM function then adds up all the numbers in the column.

The candidate's solution correctly calculates the sum of all even numbers in the array. However, the solution could be more concise. For example, the candidate could have used the built-in SUM function to calculate the sum, rather than creating a new table.
