Web5 jul. 2024 · Priority Queue implemented using a Heap. A heap is a tree data structure that keeps to max or min element at the root. So you can have a max-heap or min-heap. Regardless, they have two basic operations: insert and remove. Conceptually the heaps can be represented as a complete binary tree. WebHere are time complexities of various heap data structures.
