Heap (data structure)

In computer science, a heap is a specialized tree-based data structure that satisfies the heap property: If A is a parent node of B then the key (the value) of node A is ordered with respect to the key of node B with the same ordering applying across the heap. A heap can be classified further as either a "max heap" or a "min heap". In a max heap, the keys of parent nodes are always greater than or equal to those of the children and the highest key is in the root node. In a min heap, the keys of parent nodes are less than or equal to those of the children and the lowest key is in the root node. Heaps are crucial in several efficient graph algorithms such as Dijkstra's algorithm, and in the sorting algorithm heapsort. A common implementation of a heap is the binary heap, in which the tree is a complete binary tree (see figure).

In a heap, the highest (or lowest) priority element is always stored at the root. A heap is not a sorted structure and can be regarded as partially ordered. As visible from the heap-diagram, there is no particular relationship among nodes on any given level, even among the siblings. When a heap is a complete binary tree, it has a smallest possible height—a heap with N nodes always has log N height. A heap is a useful data structure when you need to remove the object with the highest (or lowest) priority.

Note that, as shown in the graphic, there is no implied ordering between siblings or cousins and no implied sequence for an in-order traversal (as there would be in, e.g., a binary search tree). The heap relation mentioned above applies only between nodes and their parents, grandparents, etc. The maximum number of children each node can have depends on the type of heap, but in many types it is at most two, which is known as a binary heap.

The heap is one maximally efficient implementation of an abstract data type called a priority queue, and in fact priority queues are often referred to as "heaps", regardless of how they may be implemented.

A heap data structure should not be confused with the heap which is a common name for the pool of memory from which dynamically allocated memory is allocated. The term was originally used only for the data structure.

Heap (comics)

The Heap is the name of several fictional comic book muck- monsters, the original of which first appeared in Hillman Periodicals' Air Fighters Comics #3 (Dec. 1942), during the period fans and historians call the Golden Age of Comic Books. The character was created by writer Harry Stein and artist Mort Leav, and revived in the 1980s by Eclipse Comics.

Similar but unrelated characters appeared in comics stories published by Skywald in the 1970s and Image Comics in the 1990s.

Heap (mathematics)

In abstract algebra, a heap (sometimes also called a groud) is a mathematical generalization of a group. Informally speaking, a heap is obtained from a group by "forgetting" which element is the unit, in the same way that an affine space can be viewed as a vector space in which the 0 element has been "forgotten". A heap is essentially the same thing as a torsor, and the category of heaps is equivalent to the category of torsors, with morphisms given by transport of structure under group homomorphisms, but the theory of heaps emphasizes the intrinsic composition law, rather than global structures such as the geometry of bundles.

Formally, a heap is an algebraic structure consisting of a non-empty setH with a ternary operation denoted [x, y, z] ∈ H that satisfies

  • the para-associative law
[[a, b, c], d, e] = [a, [d, c, b], e] = [a, b, [c, d, e]] ∀ a, b, c, d, e ∈ H
  • the identity law
[x, a, a] = [a, a, x] = xx, a ∈ H.

A group can be regarded as a heap under the operation [x, y, z] = xyz. Conversely, let H be a heap, and choose an element . The binary operationx * y = [x, e, y] makes H into a group with identitye and inverse x = [e, x, e]. A heap can thus be regarded as a group in which the identity has yet to be decided.

Whereas the automorphisms of a single object form a group, the set of isomorphisms between two isomorphic objects naturally forms a heap, with the operation [f, g, h] = fgh (here juxtaposition denotes composition of functions). This heap becomes a group once a particular isomorphism by which the two objects are to be identified is chosen.

Douglas Harper's Etymology Dictionary


Old English heap "pile, great number, multitude" (of things or persons), from West Germanic *haupaz (cognates: Old Saxon hop, Old Frisian hap, Middle Low German hupe, Dutch hoop, German Haufe "heap"), perhaps related to Old English heah "high." Slang meaning "old car" is attested from 1924. As a characteristic word in American Indian English speech, "a lot, a great deal," by 1832.


Old English heapian "collect, heap up, bring together;" from heap (n.). Related: Heaped; heaping. Compare Old High German houfon "to heap."
