In this problem, we will find the K nearest point from the origin in the 2D plane from the given N points. We can use the standard Euclidean distance formula to calculate the distance between the origin and each given point. After that, we can store the points with distance in the array, sort the array according to the distance, and take the first K points. However, we can also use the priority queue to store the 2D points according to their distance from the origin. After that, we can deque the queue for K times. Problem statement − ... Read More
In this problem, we will convert the number N to M by adding the one prime factor of N to itself and updating it in each operation. We will use the breadth−first search algorithm to solve the problem. We will find the prime factor of each updated N and insert it into the queue after adding it to the prime factor of N. Also, we will define functions to find the smallest prime factor of a particular number. Problem statement − We have given N and M integer values. We need to count the minimum number of operations required to ... Read More
Stored Procedures are essential to database management systems (DBMS) because they boost security, increase performance, and encourage code reuse. A group of SQL statements are included within pre-compiled database objects known as stored procedures. They can be called by apps or other database objects and are saved in the database. In this post, we will go into the details of SQL Persistent Stored Modules (PSM), a procedural programming language extension for SQL, and examine the idea of stored procedures. Understanding Stored Procedures Stored Procedures are database objects that have already been pre-compiled and include a collection of SQL statements. They ... Read More
In this problem, we will convert the linked list to the complete binary tree. We can assume the linked list as an array. The pth element of the linked list is the parent node of the binary tree's 2*p + 1 and 2*p + 2 elements. So, we can traverse through each element of the linked list and construct the binary tree. Problem statement − We have given a linked list containing N nodes. We need to construct the complete binary tree from the given linked list. Also, print the in−order traversal of the binary tree. Note − In the ... Read More
We can disable a jQuery UI draggable widget with the help of its draggable disabled option. jQuery is a javascript library that helps us manipulate the DOM easily and efficiently using its various helper methods and properties. It allows us to add interactivity to the DOM as well as add and change the CSS styles of the DOM elements. Syntax $(element).draggable({ disabled: true }) We will be using the following jQuery link in our application − The above-provided code snippet is a link tag that imports the CSS file from the jQuery UI library. Example ... Read More
In this problem, we will check whether we can get the permutation of 1 to N elements given array using the BFS (Breadth−first search) traversal with the given binary tree. Here, we will traverse the tree and find all possible permutations using the BFS traversal. After that, we can check whether any BFS traversal result matches the array permutation. Problem statement − We have given an array of size containing the first N positive integers in random order. Also, we have given a tree containing the first N numbers as a tree node. We need to check whether we ... Read More
In this problem, we will check whether we can reach the array’s end by moving back or ahead by nums[p] moves from the current position. The naïve approach to solve the problem is to check all possibilities to move into the array and see if we can reach the array’s end. Another approach is using the queue and BFS traversal in the array. In this tutorial, we will learn both approaches to check whether we can reach to the end of the array. Problem statement − We have given a nums[] array containing the positive integers. Also, we have given ... Read More
What is Sorting? Sorting is the process of arranging a collection of items or data elements in a particular order, usually based on some predefined criteria. It is a fundamental operation in computer science and is used extensively in various algorithms and applications. The purpose of sorting is to bring organization and structure to a set of data so that it can be easily searched, accessed, or presented in a meaningful way. By arranging the data in a specific order, sorting allows for efficient searching, comparison, and retrieval operations. Sorting can be performed on various types of ... Read More
There are several ways to sort an array of objects by object fields in PHP. Here are some common approaches: Using usort() function with a custom comparison function Implementing a custom sorting algorithm Utilizing the array_multisort() function Using usort() Function with a Custom Comparison Function Here's an example of using the usort() function with a custom comparison function to sort an array of objects by object fields in PHP: // Custom comparison function function compareByField($a, $b) { // Replace 'fieldName' with ...

Seaborn is primarily a data visualization library and does not provide direct methods for performing calculations on data, such as calculating mean or standard deviation. However, Seaborn works seamlessly with the pandas library, which is a powerful data manipulation library in Python. You can use pandas to perform calculations on your data, and then use Seaborn to visualize the calculated results. The mean is a statistical measure that represents the average value of a set of numbers. It is calculated by summing up all the numbers in the set and then dividing the sum by the total count of numbers. ... Read More
