In this problem, we need to count the maximum string having common prefix of length K. We can take prefix of length K from all strings and count maximum number of similar prefix using the map data structure. Also, we can use the Trie data structure to solve the problem. Problem statement - We have given an strs[] array containing multiple strings. We need to count the maximum number of strings containing a common prefix of length K. Sample Example Input strs = {"tutorialspoint", "tut", "abcd", "tumn", "tutorial", "PQR", "ttus", "tuto"}; K = 3; Output ... Read More

PyTorch is based on the Torch library, which was originally developed in Lua, and it provides Python bindings. PyTorch is widely used in academia and industry for various machine learning tasks such as computer vision, natural language processing, and speech recognition. In this tutorial, we will learn how to use the PyTorch library to build a deep learning model. Getting Started Before we dive into using the torch library, ... Read More
In the field of data analysis and machine learning, data preprocessing plays a vital role in preparing raw data for further analysis and model building. Data preprocessing involves a series of steps that clean, transform, and restructure data to make it suitable for analysis. Python, with its powerful libraries and tools, provides an excellent ecosystem for building robust data preprocessing pipelines. One such library is Pandas, a popular data manipulation and analysis library that offers a wide range of functions and methods for working with structured data. In this tutorial, we will delve into the process of building a data ... Read More
In this problem, we need to find the maximum palindromic string by rearranging the characters of any substring of the given string. We will use bitmasking to solve the largest palindromic substring. If any substring has bitmasking 0, it contains all characters even a number of times. So, we can generate a palindromic string using the characters of that substring, and we need to find the maximum palindromic string among them. Problem statement - We have given a string containing the N numeric characters. We need to find the maximum palindromic string by rearranging the characters of any ... Read More
Pygame is a good game development library since it includes a variety of built-in tools and functions that can be used to create games of various genres, from simple to complicated. The library comprises graphics, sound, and input processing, all of which are required for any game. The ability to create and alter sprites is one of Pygame's most remarkable capabilities. Sprites are graphical objects that depict the game's characters, objects, and other game features. Pygame includes a robust sprite class that allows the developer to incorporate graphics and animations into the game, move and rotate the sprites, and detect ... Read More

The given task in this article is to create an Olympics logo using only HTML and CSS. The “Olympic logo” consists of five circles (with five different colors such as blue, black, red, yellow, and green) which are intertwined by equal dimensions. These five colored rings represent the five inhabited continents of the world. These are Africa, the Americas, Asia, Europe, and Oceania. Setting up the Logo Container − We start by creating an element with the class name Olympic-logo. This serves as the container for the Olympic symbol. We set its width, height, background color, position, and ... Read More
