The function should take an array of integers as input and return the sum of the odd integers in the array.
About this solution: This is a great solution! The candidate has thought through the problem and provided a detailed explanation of their approach. This solution is optimal because it uses a for loop to iterate through the array and check if each element is odd. 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.

The problem is to write a function that calculates the sum of the odd numbers in an array. An example input would be [1, 2, 3, 4, 5] and the corresponding output would be 9.
About this solution: This solution is correct and demonstrates a good understanding of how to approach this problem. The candidate has correctly identified that a for loop is the best way to iterate through the array, and has also correctly identified that only odd numbers need to be added to the sum. This is a well-thought-out solution.
