Data Structure Algorithm Problems Question and Solutions. Solving the problem using different – 2 approaches of the DSA algorithms.
Insertion Sort DSA is a simple sorting algorithm that works in similar way of playing card sorting. This algorithm splits the array into two parts, sorted and unsorted array. Values from unsorted parts are picked and placed into the correct place in sorted array. Let have try the Algorithm For example we have an array: […]

Selection Sort is a efficient and simple algorithms for sorting the elements by repeatedly selecting the largest or smallest element from the unsorted portion of the list and moving it to the sorted portion of the list. Lets go in deep dive. Steps to follow for Selection Sort Algorithms In this type of sort, pick

Bubble sort in DSA is a basic Data Structure Algorithm, generally asked in almost all interviews. After the many interviews survey it found that almost 80% interviewee asks this bubble sort question. So in this tutorial we will learn about sorting an array or list using the bubble sort algorithms. We will sort an array

Factorial of a number in computer science and mathematics, the factorial of a non-negative integer n, denoted as n!, is the product of all positive integers less than or equal to n. It is defined as follows: �!=�×(�−1)×(�−2)×…×2×1n!=n×(n−1)×(n−2)×…×2×1 Here’s an explanation of how to calculate the factorial of a number using examples in Java, PHP,

To check whether a binary tree is a Binary Search Tree (BST) or not. First we need to ensure that the properties of a BST are satisfied. A binary tree is a BST if for every node. The values in its left subtree are less than the node’s value. And the values in its right
Check Tree is a BST or not Full Explanation Read More »
In a binary search tree (BST), a postorder traversal is a way to visit all the nodes of the tree in a specific order. In a postorder traversal, we first visit the left subtree, then the right subtree, and finally the root node. This means that the nodes are processed in a “left-right-root” order. What

Preorder traversal is a depth-first traversal technique used to visit all nodes in a binary search tree (BST). In this type traversal, you visit the root node first, then traverse the left subtree, and finally, traverse the right subtree. The process is recursive, which means you apply the same rule to each subtree until all

Inorder traversal is a way to visit all the nodes of a binary tree in a specific order. For BST, the inorder traversal visits the nodes in ascending order of their values. Binary Search Tree (BST): A binary search tree is a binary tree data structure where each node has at most two children, commonly

A Binary Search Tree (BST) is a Binary Tree data structure that follows a specific ordering property. It is organized in such a way that for every node, all the values in its left subtree are smaller than its value, and all the values in its right subtree are greater than its value. This ordering

In this example we will see the major differences about the Binary Tree and Binary Search Tree. Please see the full details below to explore the differences. See the full difference below. What is Binary Tree? A binary tree is a type of data structure in which each node has at most two children. Referred

In this tutorial we will learn how to do Searching operation in Node in Binary Search Tree. Please see the full details below for learn about this. A Binary Search Tree (BST) is a type of binary tree data structure that follows a specific ordering principle. It provides an efficient way to store and retrieve

A binary search tree (BST) is a type of binary tree that follows a specific ordering property. Making it efficient for searching and inserting elements. It is a data structure in which each node has at most two children, referred to as the left child and the right child. Additionally, the values stored in the

In this example we will see that Why String are Immutable in Java. In Java, strings are immutable, which means that once a string object is created, its content cannot be changed. This design decision was made for several reasons: To provide an alternative for situations where dynamic string manipulation is needed, Java provides the

Minimize the maximum difference between any two heights by either increasing or decreasing the heights. We are allowed to change the height of each element by at most k units. In this problem, we can sort the array in ascending order and then adjust the heights to minimize the maximum difference. By increasing or decreasing

To write a program to provided implements the cyclically rotate of an array by one position. Cyclic rotation involves moving each element of the array one position to the right, with the last element moving to the first position. This operation can be useful in various scenarios, such as shifting elements in a circular manner
