The function should take in an array of integers and return the sum of the elements in the array.

About this solution: This is a great solution! The candidate has clearly thought through the problem and has provided a very efficient solution.

This technical problem involves writing a function that takes an array of integers as input and returns the sum of the integers in the array. An example input and output are provided in the problem statement.

About this solution: This is a great solution! The candidate has used the reduce method, which is an efficient way to iterate over an array and return a single value.

This technical problem deals with determining whether a string of parentheses is balanced. A string is considered balanced if there are an equal number of open and closed parentheses, and each open parentheses is matched with a closed parentheses.

About this solution: This solution is correct and demonstrates a good understanding of the problem. The approach is simple and efficient, and the code is clean and easy to read.

This function takes in a string as input and returns the same string with the first letter of each word capitalized.

About this solution: This solution is correct and demonstrates a good understanding of time and space complexity.

The function should take an array of integers as input and return the sum of the odd numbers in the array.

About this solution: This is a great solution! The candidate has thought through the problem and provided a complete solution that solves the problem. The candidate has also taken care to optimize the solution, which is great to see.
