How are sets implemented in different programming languages?
Sets are data structures that store unique elements. In Python, they are implemented using a hash table, while in Java, the HashSet class is used.
What about in JavaScript?
In JavaScript, sets are implemented using the Set object, which allows you to store unique values of any type.
Can you explain how sets work in C++?
In C++, sets are implemented using the STL set container, which is typically based on a balanced binary tree, ensuring elements are sorted.
Are there any performance differences between these implementations?
Yes, performance can vary. For example, Python's set operations are generally O(1) for add and check, while C++'s set operations are O(log n) due to the tree structure.
