What is the time complexity of different data structures in C++?
An example of an AI chatbot conversation about C++ data structure complexities.
What is the time complexity of different data structures in C++?
In C++, the time complexity varies by data structure. For example, arrays have O(1) access time, while linked lists have O(n).
Can you explain why linked lists have O(n) access time?
Linked lists require traversal from the head to the desired node, leading to O(n) time complexity for access.
What about the time complexity for insertion and deletion in these structures?
Insertion and deletion in linked lists are O(1) if you have a pointer to the node, while in arrays, they can be O(n) due to shifting elements.
How does the complexity change with different types of trees?
In binary search trees, average case insertion and search are O(log n), but in the worst case, they can degrade to O(n) if unbalanced.
