Binary heap priority queue

WebImplementation of Heaps. A heap implements a priority queue as a complete binary tree. In a binary tree, each node will have at most two children. In a complete binary tree, all levels except possibly the deepest one are full at all times. If the deepest level is incomplete, then it will have the nodes as far to the left as possible. WebQuestion. Construct a priority queue using a heapordered binary tree, but instead of an array, use a triply linked structure. Each node will require three links: two to go down the tree and one to traverse up the tree. Even if no maximum priority-queue size is specified ahead of time, your solution should ensure logarithmic running time per ...
