To reverse a string without using any built-in string methods, you can loop through the string and build a new string with the characters in reverse order.
The candidate's solution is correct and demonstrates a level of completeness. The solution uses a for loop to iterate through the string, starting from the end and adding each character to a new string. This is optimal because it is O(n) time complexity and O(n) space complexity.
