Heap Data Structure is a special case of balanced binary tree data structure where the root-node key is compared with its children and arranged accordingly. Min-Heap − Where the value of the root node is less than or equal to either of its children. Max-Heap − Where the value of the root node is greater ...
A stack in data structure, following the Last In First Out (LIFO) principle, is a crucial linear data structure for sequential task completion. Imagine entering a crowded elevator last and exiting first; this mirrors stack behavior. Understanding this, we’ll explore the formal definition of a stack data structure in C++. Some Key Points Related to ...
Bubble Sort, a basic sorting algorithm, operates by repeatedly swapping adjacent elements if they are incorrectly ordered. Consider a list with elements 5, 4, 3, and 2; sorting algorithms like Bubble Sort can organize them in either ascending or descending order, rearranging elements to form meaningful sequences, as illustrated in this example. Ascending Sorting Descending Sorting ...
The selection sort algorithm efficiently arranges elements into two sections: sorted and unsorted sublists. This method simplifies list organization, enhancing sorting efficiency. In this article, we delve into the mechanics of selection sort, explaining its process and effectiveness in sorting various types of lists. Let’s explore what selection sort is and how it works. Takeaways ...
This article delves into the Heapsort Algorithm, a prominent and efficient sorting technique in computer programming. It operates by creating a min-heap or max-heap from the array’s elements, where the root signifies the minimum or maximum value. Heap sort involves two primary recursive operations: building a heap (H) using array elements and repetitively deleting the ...
Quicksort is a prominent divide-and-conquer-based sorting algorithm renowned for its efficiency. Operating by selecting a pivot and partitioning the array around this pivot, Quicksort places the pivot in its correct sorted position. This technique achieves an average of nlogn comparisons for sorting n elements, making it notably swift. The algorithm’s essence lies in its divide-and-conquer approach: it breaks down ...
A binary tree is a tree-type non-linear data structure with a maximum of two children for each parent. Every node in a binary tree has a left and right reference along with the data element. The node at the top of the hierarchy of a tree is called the root node. Takeaways A binary tree is the specialized version of the ...
