A binary heap is defined as a binary tree with two additional constraints: [3] Shape property: a binary heap is a complete binary tree; that is, all levels of the tree, except possibly the last one (deepest) are fully filled, and, if the last level of the tree is not complete, the nodes of that level are filled from left to right.
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.
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.
Binary or Intel hex: .obj , .obl , [ 8 ] .obh , [ 8 ] .rom , .eep Intel hexadecimal object file format , Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [ 10 ] making it possible to store on non-binary media such as paper tape , punch cards , etc., to display on text terminals or be printed ...
He worked with Donald E. Knuth to develop a two-heap data structure that they called a "priority deque", published as an exercise in The Art of Computer Programming in 1973. [ 18 ] [ 19 ] After moving to Canada in 1974, he worked for Bell-Northern Research Ltd., Ottawa (BNR) and Northern Telecom (Nortel) until retiring in 1995.
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.

Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
