WebRaw Blame. //Prority queue implementation using max binary heap implementation using complete binary tree. //using array in background. //all content inserted into the heap is stored in data array. //incase insertion exceeds array size, it automatically. //doubles the array's size, resizing can also be done through. WebExample. 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.
