A heap is a tree-based data structure that satisfies the heap property: in a max heap, the parent node is greater than or equal to the child node, and vice versa for a min heap. Learn about the operations, implementation, and variants of heaps, such as binary heaps, 2–3 heaps, and B-heaps.
A Fibonacci heap is a data structure for priority queue operations, consisting of a collection of heap-ordered trees. It has a better amortized running time than many other priority queue data structures, and is named after the Fibonacci numbers used in its analysis.
A binomial heap is a data structure that acts as a priority queue and supports merging two heaps in logarithmic time. It is implemented as a set of binomial trees, which are defined recursively and have a special shape based on binary coefficients.
A binary heap is a complete binary tree that satisfies the heap property: the key in each node is either greater than or equal to (max-heap) or less than or equal to (min-heap) the keys in the node's children. Learn how to insert, extract, decrease-key and merge elements in a binary heap with O (log n) time complexity.
Heapsort is an in-place algorithm that divides its input into a sorted and an unsorted region, and iteratively shrinks the unsorted region by extracting the largest element from it and inserting it into the sorted region. It uses a binary heap data structure to efficiently find the largest element in each step, and has a worst-case runtime of O (n log n).
A Fenwick tree or binary indexed tree (BIT) is a data structure that can efficiently update values and calculate prefix sums in an array of values. This structure was proposed by Boris Ryabko in 1989 [ 1 ] with a further modification published in 1992. [ 2 ]
A pairing heap is a type of heap data structure with relatively simple implementation and excellent practical amortized performance, introduced by Michael Fredman, Robert Sedgewick, Daniel Sleator, and Robert Tarjan in 1986. [1] Pairing heaps are heap-ordered multiway tree structures, and can be considered simplified Fibonacci heaps.
A data structure is a data organization and storage format that is usually chosen for efficient access to data. Learn about different types of data structures, such as arrays, lists, graphs, trees, and hash tables, and how they are implemented and used in computer science.
