WebHeaps. A heap is a tree-based data structure in which all the nodes of the tree are in a specific order. For example, if X is the parent node of Y, then the value of X follows a specific order with respect to the value of Y and the same order will be followed across the tree. The maximum number of children of a node in a heap depends on the ... WebThis helps us to efficiently implement one sorting algorithm called heap sort and a priority queue. A binary heap can be efficiently implemented using an array (static or dynamic). To implement a binary heap of height h, we need O(2 h) memory blocks and we insert the items in the array following level-order (breadth first) of a tree. Figure 2 ...
