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 tree based data structure where the tree is a complete binary tree that maintains the property that either the children of a node are less than itself (max heap) or the children are greater than the node (min heap).
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.

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.
