While Tkinter excels in creating dynamic applications, certain challenges arise when attempting to manipulate the positions of widgets. In this tutorial, we will explain an advanced Tkinter technique and show how you can move a button beyond its parent's confines. Understanding Tkinter Hierarchy Tkinter follows a hierarchical structure where widgets are nested within their parent widgets. A widget's position and visibility are constrained within the boundaries of its parent. This limitation can be a hurdle when attempting to move a widget outside its parent's area. However, by utilizing Toplevel windows, we can create a workaround to overcome this constraint. Creating ... Read More
Multithreading is a powerful concept in programming, allowing developers to execute multiple tasks concurrently and improve overall program performance. In Python, the threading module provides a convenient way to implement multithreading. When working with threads, it's often necessary to receive callbacks to handle events or synchronize the execution of different threads. In this tutorial, we'll explore various techniques for receiving thread callbacks in Python. Threads in Python Before delving into thread callbacks, let's briefly review the basics of threading in Python. The threading module offers a high-level interface for creating and managing threads. Threads are lightweight processes that share the ... Read More
Introduction The coordinate graph is also called the Coordinate grid or plane. In a coordinate grid, the two perpendicular lines are called the axes. The horizontal axis is called the $\mathrm{x\:-\:axis}$ and the vertical axis is called the $\mathrm{y\:-\:axis}$ In a grid, points are distributed on the number lines, namely, on the $\mathrm{x\:-\:axis}$ and the $\mathrm{y\:-\:axis}$ The points of contact are written in the ordered pair. By reading the latitude and longitude of the coordinate plane, the location of the points on the grid can be found. The points on the $\mathrm{x\:-\:axis}$ is called the ... Read More
Introduction Linear programming or linear optimization is a unique tool used to obtain the optimum (maximum or minimum) value of a mathematical model. It is abbreviated as LP and it is also known as mathematical optimization. In this tutorial, we will learn about linear programming, different methods to solve linear programming problems, and its various types. Linear Programming Linear programming is defined as the mathematical optimization process in which the maxima and minima of the process outcomes are evaluated within specific constraints. In other words, it is a technique to optimize the linear objective function. ... Read More
In this article, we will discuss about a special type of number called fibonomial coefficient and how does a fibonomial triangle looks like. We will also discuss the C++ code approach to print a fibonomial triangle with a given height. Let us first discuss that what is a fibonomial coefficient. Fibonomial Coefficient We can call a fibonomial coefficient a generalisation of well known terms namely , Fibonacci numbers and binomial coefficients. The Fibonacci numbers are a series of numbers in which, each number is the sum of the two preceding numbers (for example − 0, 1, 1, 2, 3, 5, ... Read More
Introduction The scalar triple product is used to find the volume of parallelepiped, which is a 3 dimension of parallelogram. As it is a triple product it deals with the three vectors on the three adjacent edges starting from a common vertex. $\mathrm{volume\:of\:parallelepiped\:=\:\overrightarrow{a}\:.\:(\overrightarrow{b}\:\times\:\overrightarrow{c})}$ We know the area of base of parallelepiped is the area of a parallelogram $\mathrm{=\:l\:\times\:b}$ $\mathrm{Area\:of\:the\:base\:=\:\lvert\:\overrightarrow{b}\:\times\:\overrightarrow{c}\:\rvert}$ To find the height of the Parallelepiped, b × c is a perpendicular line drawn to b and c which is not the actual height of parallelepiped. We first consider the height of the cuboid and convert it into parallelepiped. ... Read More
Introduction Integers are one of the most important concepts in mathematics, and most of them are relevant to this topic. You can practice this concept by practicing multiple integer worksheets. In mathematics, integers are characterized as numbers with a possible value of either positive, negative, or zero. These figures, however, cannot constitute a fraction. These numbers can be used to carry out a variety of mathematical operations, including addition, subtraction, multiplication, and division, according to the integer worksheet. According to the integer worksheet, examples of integers include 1, 2, 5, 8, -8, - ... Read More
In this article, we will discuss a simple program which calculates the factorial of all the numbers present in the Fibonacci series smaller than a given nums. Problem Statement We are given a number and our task is to generate the factorial of all the numbers present in the Fibonacci series and smaller than the given number. Let us first understand the problem statement and requirements from the code solution with the help of examples. Input nums = 13 Output Fibonacci series up to 13 is 0, 1, 1, 2, 3, 5, So, the factorial ... Read More
We will discuss two approaches to solve the sword puzzle. In the first approach, we will use circular linked list, while the second approach is based on general intuition. In this article, we will discuss what is a sword puzzle problem and how we can solve a sword puzzle problem. Problem Statement We have an arrangement of n people in a circle in which, first person is carrying a sword. The first person kills the second person and hands over the sword to the next alive person in the circle. Now the next person carrying the sword kills the next ... Read More
The analysis and manipulation of strings are fundamental operations in many applications of computer programming. Counting subsequences with the pattern "01" in a string formed by repetitively concatenating a given numeric string poses an interesting challenge. The primary question is determining the total count of such subsequences in the resulting string. This article discusses a useful C++ approach to solve this issue successfully and offers a solid answer to deal with this particular work. Concept of Subsequence A subsequence is a sequence of characters that is derived from some other sequence by eliminating zero or more characters without altering the ... Read More
