What is the time complexity of Heap push/pop?
Updated Apr 28, 2026
Short answer
O(log N) for both insertion and removal of the top element.
Deep explanation
Heaps and Maps are fundamental for optimization. O(log N) for both insertion and removal of the top element. Heaps are used for priority management, while Maps provide constant-time data retrieval.
Real-world example
Priority queues in operating systems.
Common mistakes
