Merge two sorted arrays in Python using heapq
Heap Heap Data structure primarily focuses on representing priority queue. In Python, there is an inbuilt module “heapq” which is used for implementing Heap data structure. By default, Min Heap...
Python Queue using Doubly Linked List
A queue is an ordered collection of elements in which the addition of one element happens at one end known as REAR and the removal of existing elements occurs at...
Python Program for Heap Sort
Given an array, we have to sort it using heap sort. Heap Sort is a sorting algorithm based on the binary heap data structure in which first we have to...
Queues in Python
The queue is a linear data structure that works on the principle of First in First out (FIFO). In the queue, the element which is added at least recently is...
Priority Queue in Python
Priority Queue Priority queues are abstract data structures where each element in the queue has a priority value. For example, in any airline, baggage under the “First-Class” or “Business” arrives...
Stack and Queues in python
In data structures, stack and queue are part of linear data structure. Stack Stack follows the principle of LIFO (Last in First out) i.e. element which is inserted at last...
How are variables stored in python – Stack or Heap?
Memory allocation is the process of allocating memory to a computer program. In Python, the process of memory allocation and deallocation is handled automatically as there is a garbage collector...
Implementation of Min Heap in Python
What is Heap? Heap Data structure primarily focuses on representing priority queue. Min - Heap follows the property of a complete binary tree in which the value of the internal...
Implementation of Max Heap in Python
A heap is simply a binary tree with some additional rules that it has to follow. There are two rules which differentiate heap structures from any other tree structure. Rules...
