Mar 30, 2024 · A Heap is a complete binary tree data structure that satisfies the heap property: for every node, the value of its children is less than or equal to its own value. Heaps are usually used to implement priority queues, where the smallest (or largest) element is always at the root of the tree.
- Heapify. Heapify is the process of creating a heap data structure from a binary tree. It is used to create a Min-Heap or a Max-Heap. Let the input array be.
- Insert Element into Heap. Algorithm for insertion in Max Heap. If there is no node, create a newNode. else (a node is already present) insert the newNode at the end (last node from left to right.)
- Delete Element from Heap. Algorithm for deletion in Max Heap. If nodeToBeDeleted is the leafNode remove the node Else swap nodeToBeDeleted with the lastLeafNode remove noteToBeDeleted heapify the array.
- Peek (Find max/min) Peek operation returns the maximum element from Max Heap or minimum element from Min Heap without deleting the node. For both Max heap and Min Heap.

Aug 7, 2023 · A Heap is a special Tree-based Data Structure in which the tree is a complete binary tree. Types of heaps: Generally, heaps are of two types. Max-Heap: In this heap, the value of the root node must be the greatest among all its child nodes and the same thing must be done for its left and right sub-tree also.
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 a parent node of C, then the key (the value) of P is greater than or equal to the key of C.
Oct 1, 2023 · A heap is defined by two properties. First, it is a complete binary tree, so heaps are nearly always implemented using the array representation for complete binary trees . Second, the values stored in a heap are partially ordered . This means that there is a relationship between the value stored at any node and the values of its children.
Oct 14, 2019 · Heap is a special case of balanced binary tree data structure where the root-node key is compared with its children and arranged accordingly. If α has child node β then −. key (α) ≥ key (β) As the value of parent is greater than that of child, this property generates Max Heap.
A Heap is a specialized tree-based data structure that satisfies the heap property. It’s essentially an array visualized as a nearly complete binary tree. Heap Properties. There are mainly two types of heaps: Max-Heap: In a Max-Heap, for any given node N, the value of N is greater than or equal to the values of its children.
