Word Origin & History

heap
O.E. heap "pile, great number, multitude," from W.Gmc. *khaupaz (cf. O.S. hop, M.L.G. hupe, Du. hoop, Ger. Haufe "heap"), probably related to O.E. heah "high." The verb is from O.E. heapian. Slang meaning "old car" is attested from 1924.

heap definition


1. An area of memory used for dynamic memory allocation where blocks of memory are allocated and freed in an arbitrary order and the pattern of allocation and size of blocks is not known until run time. Typically, a program has one heap which it may use for several different purposes.
Heap is required by languages in which functions can return arbitrary data structures or functions with free variables (see closure). In C functions malloc and free provide access to the heap.
Contrast stack. See also dangling pointer.
2. A data structure with its elements partially ordered (sorted) such that finding either the minimum or the maximum (but not both) of the elements is computationally inexpensive (independent of the number of elements), while both adding a new item and finding each subsequent smallest/largest element can be done in O(log n) time, where n is the number of elements.
Formally, a heap is a binary tree with a key in each node, such that all the leaves of the tree are on two adjacent levels; all leaves on the lowest level occur to the left and all levels, except possibly the lowest, are filled; and the key in the root is at least as large as the keys in its children (if any), and the left and right subtrees (if they exist) are again heaps.
Note that the last condition assumes that the goal is finding the minimum quickly.
Heaps are often implemented as one-dimensional arrays. Still assuming that the goal is finding the minimum quickly the invariant is
heap[i] where heap[i] denotes the i-th element, heap[1] being the first. Heaps can be used to implement priority queues or in sort algorithms.

Heap definition


When Joshua took the city of Ai (Josh. 8), he burned it and "made it an heap [Heb. tel] for ever" (8:28). The ruins of this city were for a long time sought for in vain. It has been at length, however, identified with the mound which simply bears the name of "Tel." "There are many Tels in modern Palestine, that land of Tels, each Tel with some other name attached to it to mark the former site. But the site of Ai has no other name 'unto this day.' It is simply et-Tel, 'the heap' par excellence."

Easton's 1897 Bible Dictionary
