In this problem, we need to check whether the given number is an unsigned integer using the DFA. We need to construct the DFA using the 2D array to solve the problem. Problem statement – We have given string str of length N. By constructing the DFA, we need to check whether the str represents the unsigned integer. In the output, print ‘unsinged integer’ or ‘Not an unsinged integer’ according to whether the number is unsinged or not. Sample examples Input– str = "1729" Output– “Unsigned integer.” Explanation– As the number doesn’t contain any sign, it is an ... Read More
The problem is stating that we have to add two binary strings. Binary strings are a sequence of bytes. To add them in javascript, we will first convert them to decimal and calculate the sum. After adding those decimal numbers, we will convert it again into binary strings and print the output. What are Binary Strings? Binary numbers or binary strings are sequences of bytes in base 2. It is basically a combination of 0 and 1 to represent any number. While binary addition is one of the operations of mathematics to perform on binary strings. Binary addition ... Read More
In this problem, we need to check whether we can make two strings equal by rearranging the words of the string. We will learn three different approaches to solving the problem. In the first approach, we will use a dictionary. In the second approach, we will use the sort() method, and in the third approach, we will use the counter() constructor, which is used to count the hashable objects in the python. Problem statement – We have given a str1 and str2 containing sentences. We need to check whether we can make both strings equal by rearranging the words of ... Read More
A dictionary in Python is a built-in data structure that allows you to store and retrieve values using unique keys. It is an unordered collection of key-value pairs enclosed in curly braces {}. Dictionaries provide a convenient way to organize and manipulate data, making it easy to access values based on their corresponding keys. In this article, we are going to see how to convert Dictionary to Concatenated String using Python which means that all the keys and values of the dictionary will be combined in the form of a string as follows. Input = {'one': 1, 'two': 2, ... Read More
Data handling or organizing or structuring in Python has a lot of common tasks and 1 such task is the conversion of list to list of dictionaries. It is a simple process that allows us to associate specific keys with their corresponding values; creating a collection of dictionaries that can be simply accessed and/or manipulated. Before going forward with the techniques let us 1st see an example input and output. Consider the following: Input test_list = ['John', 25, 'Smith', 30, 'Alice', 35] key_list = ['name', 'age'] Output [{'name': 'John', 'age': 25}, {'name': 'Smith', 'age': 30}, {'name': 'Alice', 'age': ...

When we speak of "converting an image into string format and back again in Python", this refers to converting image files to something that can be stored and managed using strings of characters, before eventually returning it back into its original image format. Converting Image to String − Converting images to strings involves transcribing their binary data into text format for transmittal or storage over network protocols that require text-based images. This conversion method can help us transmit or store an image more efficiently when working with APIs, databases or sending images over network protocols requiring text data transmission or ...

Python’s Turtle library is used for generating 2D graphics and animations. It has a very simple interface with help of which we can create shapes and patterns on the screen. It comes with some built-in shapes like squares, circles, triangles etc. However, we can even create our own shapes with the help of Turtle. In this article, we are going to see how to create custom turtle shapes in python. Before going forward with the creating custom shapes we need to install Turtle on the system and this can be done by simply using the following command − pip install ... Read More
Bootstrap is a popular front−end framework that makes it easier to design and develop responsive and mobile−first websites. It provides several components and plugins that can be used to create an add−to−cart button and implement this functionality on a website. It contains pre−built styles and functionality that can save time and effort . Algorithm Load the necessary libraries and files using Content Delivery Network (CDN). Define the HTML structure of the page, including the product image, name, description, price, and "Add to Cart" button. Define the modal window structure that will appear when the "Add to Cart" button is ... Read More
Checkboxes are a type of graphical user interface (GUI) element. It enables users to select 1 or more options from a given set of choices. They are often represented in the form of small square boxes which can be either checked(selected) or unchecked(deselected). Checkboxes are normally in square shape and are on almost all forms on the internet depending upon the use case scenarios. The KivyMD framework of python is built on top of the Kivy library that allows developers to build cross-platform applications along with GUI’s. KivyMD consists of a large set of Material Design widgets which can ... Read More
KivyMD is a commonly known library of Python which offers us with a collection of Material Design (MD) compliant widgets. These widgets can be used along with the kivy framework which is another library and is used for creating multi-touch applications. The large number of UI elements that kivyMD provides us with, include buttons, cards, dialogs, menus and many more such elements, all of which are designed to give an appealing look and feel. A navigation bar is a UI element that allows users to “navigate” between different screens/sections of an application. They are normally present on the top ... Read More
