Introduction In this tutorial, we implement an approach to check substring is palindrome by replacing its K characters for Q queries. Palindromes are words that read the same in both directions. When you read a palindromic word from a forward or backward direction, it sounds the same. For example, madam, refer. Here, Q queries are a numeric array containing the starting index, ending index, and value of K. The starting and ending index values for the input string are used to select only those characters that lie between these starting and ending index values (both values are inclusive). For the ...

Introduction This tutorial examines the definition of the advance-decline ratio, which calculates the ratio of rising to falling equities over a given period of time. We go over its computation, variations, benefits and drawbacks, and interpretation. We have also given examples and stress the value of using the ratio in conjunction with other indicators to help make educated decisions. Meaning of Advance-Decline Ratio The advance-decline ratio is a financial statistic used to assess the overall health of a stock market or particular market index and gauge the depth of market participation. It is determined by dividing the total number of ... Read More
DIV tag is nothing but a division tag, the name itself indicates that it makes divisions for the content on the web pages. It helps in separating the data like text, images, navigation bar etc., we can also create particular sections by using the DIV tag. A DIV tag consists of open and close tags , and both these tags are compulsory if we want to divide the page. DIV tags can be styled with CSS or manipulated with JavaScript, it is easily styled by using the class or id attribute. Any sort of data can be placed inside ... Read More

The Pearson Correlation Test is a simple statistical method in Python that measures the relationship between two parameter variables. It is useful to measure the relationship between two variables graphically, so you can know how strong the relationship is between the variables and whether they are related or not. To find Pearson Correlation we can use pearsonr() function. Its value falls between -1 and 1, with -1 being a perfect negative correlation, 0 representing no relationship, and 1 representing a perfect positive correlation. Syntax This syntax is used in all the following examples. pearsonr(variable1, variable2) Algorithm Step ... Read More
The Pearson Type-3 Distribution is a continuous probability distribution that is widely used in statistics. It has a skewed distribution. Three parameters determined the shape of distribution: location, scale, and shape. Discovering this type of distribution would enable statisticians to analyse their data more effectively and make more precise predictions. We can use pearson3.rvs function to generate random numbers from the distribution, and calculate the pdf (probability density function) at a given point with the help of pearson3.pdf function. Parameters of Pearson type-3 distribution Shape parameter − This parameter determines the spread through the probability density of the distribution. ... Read More
The Pi method or Pi Syntax is used to decorate a function or method in Python, and is known as a decorator. The pie method is used to modify the behaviour of a function or method. Pie Syntax (@) can be used by simply placing the @ symbol and the name of the decorator function above the definition of the function. When the function is invoked, Python is instructed to use the decorator. Pie Syntax (@) has the benefit of allowing for more adaptability in function calls. When working with complicated data structures or when you need to put in ... Read More
The Pendulum Module is used in Python for datetime manipulation and time zone management. Using this module, you can manage date, time, and other related things over time. The Pendulum Module's ability to manage time zones easily is one of its main advantages. It makes it simple to deal with dates and times from all around the world since it can instantly convert between various time zones. The Pendulum Module is a powerful tool for anyone who is dealing with time-sensitive data.

The bezier is an inbuilt drawing function in python. It is used to draw curves in python according to given points. The quadratic bezier is a Python function that draws a path through vertices( control points) for a quadratic bezier wind. A quadratic Bezier wind is a parametric wind that defines a path in 2- dimensional space. This wind is linked by a control point with two ending points. In a visualisation programme, you may construct and draw easily using this function. With the use of the time parameter, you may locate two control points and determine their locations. You ...

Introduction A File Transfer Protocol (FTP) server is a network protocol that allows users to transfer files between computers over internet or a local area network (LAN). FTP servers are commonly used in businesses and organizations for file sharing and storage. In this article, we will discuss how to configure an FTP server using Cisco Packet Tracer. Setting up FTP server Before configuring an FTP server, we need to have a server machine and an FTP client machine. In this example, we will be using two virtual machines (VMs) on Cisco Packet Tracer, one acting as FTP server and other ... Read More
