Example of a binary max-heap with node keys being integers between 1 and 100. In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key (the value) of P is greater than or equal to the key of C.
Example of a complete binary max-heap Example of a complete binary min heap. A binary heap is a heap data structure that takes the form of a binary tree.Binary heaps are a common way of implementing priority queues.
Heap (data structure), a data structure commonly used to implement a priority queue; Heap (mathematics), a generalization of a group; Heap (programming) (or free store), an area of memory for dynamic memory allocation; Heapsort, a comparison-based sorting algorithm; Heap overflow, a type of buffer overflow that occurs in the heap data area
The heapsort algorithm can be divided into two phases: heap construction, and heap extraction. The heap is an implicit data structure which takes no space beyond the array of objects to be sorted; the array is interpreted as a complete binary tree where each array element is a node and each node's parent and child links are defined by simple arithmetic on the array indexes.
Heap is a surname. Notable people with the surname include: Bob Heap, English footballer; Brian Heap, British biologist; Dan Heap, Canadian politician; David Porter Heap, American engineer; Fred Heap, English footballer; Imogen Heap, British singer-songwriter; Jessica Heap, American actress; John Heap, British geographer; Mark Heap, British actor
A min-max heap is a complete binary tree containing alternating min (or even) and max (or odd) levels.Even levels are for example 0, 2, 4, etc, and odd levels are respectively 1, 3, 5, etc.
The heap of a group may be generalized again to the case of a groupoid which has two objects A and B when viewed as a category. The elements of the heap may be identified with the morphisms from A to B, such that three morphisms x , y , z define a heap operation according to [ x , y , z ] = x y − 1 z . {\displaystyle [x,y,z]=xy^{-1}z.}
A B-heap is a binary heap implemented to keep subtrees in a single page. This reduces the number of pages accessed by up to a factor of ten for big heaps when using virtual memory, compared with the traditional implementation. [1] The traditional mapping of elements to locations in an array puts almost every level in a different page.
