Odd Index Sum

Given a list of integers, this function will return the sum of the integers at the odd indices. For example, given the input list [1, 2, 3, 4, 5], the function will return 9.

Problem

```Given a list of integers, return the sum of the integers at the odd indices.
Input: [1, 2, 3, 4, 5]
Output: 9```

```// Solution:

function sumOddIndices(arr) {
let sum = 0;
for (let i = 0; i < arr.length; i++) {
if (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 add the values at the odd indices to a sum variable.
// The for loop is optimal because it is the most efficient way to iterate through an array.
// The if statement is optimal because it is the most efficient way to check if the index is odd.
// The sum variable is optimal because it is the most efficient way to store the sum of the values at the odd indices.
// The return statement is optimal because it is the most efficient way to return the sum variable.```

A.I. Evaluation of the Solution

The candidate's solution is correct and efficient. The for loop is the most efficient way to iterate through an array, and the if statement is the most efficient way to check if an index is odd. The sum variable is the most efficient way to store the sum of the values at the odd indices. The return statement is the most efficient way to return the sum variable.
