Quantum computing is an emerging field that utilizes the principles of quantum mechanics to perform computations more efficiently than classical computers. Qiskit, a powerful open-source framework, provides a user-friendly platform to develop and execute quantum programs in Python. In this tutorial, we will explore the concept of classical NOT logic gates implemented with quantum circuits using Qiskit. Classical NOT Logic Gate The classical NOT gate, also known as an inverter, is a fundamental logic gate that takes a single input and produces the logical complement of that input. In other words, if the input is 0, the output is 1, ... Read More
Django is a popular web framework for building complex and scalable web applications in Python. One of the key design principles of Django is the use of views to handle HTTP requests and generate responses. In Django, views can be implemented using either class-based views or function-based views. Both types of views offer their own set of advantages and disadvantages, and choosing the appropriate type of view for your application depends on your specific requirements and development style. Function-based views are the traditional way of implementing views in Django. These views are implemented as simple Python functions that take ... Read More
Pandas is a powerful Python library widely used for data manipulation and analysis. When working with DataFrames, it is often necessary to check whether a specific value exists within the dataset. In this tutorial, we will explore how to use the 'in' and 'not in' operators in Pandas to determine the presence or absence of a value in a DataFrame. Checking for a Value Using the "in" Operator The 'in' operator in Python is used to check if a value is present in an iterable object. In the context of Pandas, we can use the 'in' operator to verify if ... Read More
An array is a linear data structure that stores the elements and a sorted array contains all the elements in increasing order. Sorting an array by swapping the adjacent elements means we can swap the adjacent elements any number of times and we have to sort the array. We will be given two array’s first array is the array to be sorted and another array is a Boolean array that represents whether the current element is swappable or not. If the given array is of the length N then all the elements present will be from 1 to N. ... Read More
The digit sum for a given number is the sum of all the digits present in the given number. We will be given a number n and s and we have to find all the numbers which are in the range 1 to n and have the difference between the number and the sum of its digits greater than s. We will implement two approaches with the code and the discussion on time and space complexity. Input N = 15, S = 5 Output 6 Explanation For all the numbers in the range 0 to 9, the difference ...

Programming languages are used for many purposes such as making websites, developing mobile applications, etc. Graphic designing is one of the things that we can do by using the programming language. While graphic designing, we can face a problem where we have to project a 3-D object on the 2-D plane and due to which one dimension will be reduced or one face will be hidden. In this problem, we have to detect that hidden face. Back-Face detection is also known as the name Plane Equation method, and it is a method for the object space methods in which objects ...

Co-prime numbers are numbers that do not have any common divisor other than 1. We will be given two numbers n and m. We have to find the largest number in the range of 2 to n (both inclusive) which is co-prime with all the elements in the range of 2 to m (both inclusive). If none of the elements in the given range is co-prime with all the elements of the second range then we have to return or print -1. We will implement the approach, and code, and will discuss the time and space complexity of the program. ... Read More
P smooth numbers are the numbers that have the maximum prime number that can divide them is less than or equal to the given number P. Prime numbers are the numbers that are divisible by only 1 and that number. 1 is by default considered as the P - smooth number for any given value of P. In this problem, we will be given a value P and the range and we have to return the number of elements that are present in that range and are P-smooth. Input Given the value of P is 7 and the range ... Read More
In computer systems, memory is a hardware component of the system that stores data and information in the computer. The computer memory can be classified into two main types namely – primary memory and secondary memory. The primary memory is further divided into two main types – RAM and ROM. Read through this article to find out more about RAM and ROM and how they are different from each other. Let's start with some basics of RAM and ROM. What is RAM? RAM stands for Random Access Memory. RAM is a type of primary memory of a computer system. ... Read More
To show the schema, we can use the DESC command. This gives the description about the table structure. The following is the syntax. DESCRIBE yourDatabasename.yourTableName; Let us implement the above syntax. mysql> DESCRIBE business.student; The following is the output. +-------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+--------------+------+-----+---------+-------+ | id | int(11) | YES | MUL | NULL | | | Name | varchar(100) | YES | MUL | NULL | | +-------+--------------+------+-----+---------+-------+ 2 rows in set (0.05 ...
