Min heap with priority queue

WebA priority queue implemented with a binary heap. Time complexity. The expected cost of push, averaged over every possible ordering of the elements being pushed, and over a sufficiently large number of pushes, is O(1).This is the most meaningful cost metric when pushing elements that are not already in any sorted pattern.. The time complexity … Web28 apr. 2024 · It stores the elements in an array-backed min-heap, where the root node has the highest priority. The array heap has an initial capacity and when it gets full and we try to enqueue a new element, a new heap is created with a larger capacity. This is what we mean by the priority queue capacity.
