Answer
Keeps keys sorted. Frame the concept in practical terms so you can explain it during interview discussion.
TreeMap maintains a sorted order of keys, offering O(log n) time complexity for operations. This is beneficial when you need to iterate through products in a sorted manner, such as generating a sorted list of product IDs for a report.
