WebMay 2, 2024 · To me it seems a bit overkill to have three methods for each of left, right, and parent, but that's a question of style and I can see an argument that it's for readability of the upheap and downheap methods. On the other hand, why are all of these methods (and Swap) public? That's exposing far too much of the internal implementation. Web(C++: Heap Implementation) In class, we covered the algorithms for an array-based heap implementation, paying attention only to the keys in the heap. To use a heap to implement a priority queue, you also need to keep track of elements associated with each key. (We want extract_min to give us the element with the highest priority.

Remove the minimum from a following heap: Copy the last value in the array to the root and decrease heap's size by 1: Now heap property is broken at root: Root has two children. Swap root's value with the smallest: Heap property is broken in node 1: Recover heap property: Node 3 has no children.
