Queue Linked List Implementation
Queue: A Queue is a linear data structure. Queue follows the FIFO rule i.e. First in First out. In other words we can say the element that goes in first...
Queue Data Structure
Queue: A queue is basically a linear data structure that works on the principle of FIFO (First in First out) which means an element that is enqueued first will be...
Overview of data structures binary tree, bst, heap, and hash
Binary Tree: A Binary tree is a tree data structure in which each node has at most two children i.e. the left child and right child. Representation: A binary tree...
How to check if a given array represents a Binary Heap?
Problem Statement: Given an array of integers, how We have to check if the given array represents a binary max-heap or not. First, we’ll see what is Binary heaps and...
Height of a complete Binary tree or Binary heap with N Nodes
Every node in a binary tree has either 0 children, 1 children, or 2 children. The node is a leaf node if it has no offspring. A node is an...
Minimum element in a max heap
Problem statement: The Statement is quite straightforward given a max heap, find the minimum element present in the heap. A Max heap is a complete binary tree and in the...
Difference between binary heap, binomial heap, and Fibonacci heap
A heap is a specialized tree-based data structure that satisfies the heap property. It is commonly used to implement priority queues and efficient sorting algorithms like heapsort. The heap property...
make_heap() in C++ STL
make_heap(): make_heap() function is used to transform a sequence into a heap. Heap is a data structure in which we can place elements accordingly, and make them accessible in O(1)...
Heap Algorithm for Generating Permutations
Heaps algorithms are employed for generating all conceivable permutations of n-decimals within a number. This algorithm minimizes the need for extensive rearrangements, essentially constructing each permutation from its predecessor by...
Why is Binary Heap Preferred over BST for Priority Queue?
Binary heaps and BSTs differ in their structure, operations, and use cases. Binary heaps excel at providing efficient priority queue operations and have a simple structure. They are well-suited for...
Applications of Heap data structures
What is Heap? A heap is a complete binary tree, A complete binary tree is a binary tree in which all the levels are completely filled except the last level...
Convert BST to Min Heap
Problem Statement: In this problem, we will be given a binary search tree and we have to convert the Binary search tree into a min-heap. This condition is applied to...
C++ program for heap sort
A heap is a complete binary tree, A complete binary tree is a binary tree in which all the levels are completely filled except the last level i.e. leaf node....
Array Representation of a Binary Heap
What is Binary Heap? A Binary Heap is a complete binary tree that follows a heap ordering property. The representation is done as: Parent Node: (i-1)/2 Left Child: (2i) +...
Skew Heap
Skew Heap: So basically, Skew Heap is a heap data structure implemented as a binary tree. Skew Heap has an advantage over binary trees as skew heaps merge more quickly...
Heap Sort for decreasing order using min heap
Problem Statement: In this problem, we have given an array, and we have to sort the array in decreasing order using a min-heap. Example: Input : arr[] = {1, 50,...
