The Python Matplotlib library allows us to create visual plots from given data. To make the data easier to read and relate to the chart, we can display it in the form of a table and position it directly below the corresponding bar chart. Since the x-axis runs horizontally, we arrange the table in the same direction so that each value aligns correctly under its corresponding bar. Based on this concept, we demonstrate the diagram as follows: Steps to Align a Table to the X-axis Using Matplotlib Following are the steps to create a table and store data ... Read More
An age calculator in Python using Tkinter is a GUI (Graphical User Interface) application that allows users to determine their age based on their date of birth (DOB). To design the user interface of this application, we use various methods provided by the Tkinter library such as Tk(), pack(), Entry(), Button(), and more. GUI of Age Calculator Let us build a GUI-based age calculator where the user can enter their age in the format of years, months, and days. Ensure that single-digit numbers are prefixed with a 0. Creating an Age Calculator Application using Python Tkinter To create an ... Read More
All possible concatenations in a string list means to generate every possible combination of strings by concatenating two or more elements from a given list of strings. In this article, we are given a string list and we need to find all its possible concatenations. Following are the input-output scenarios for concatenating string's list: Scenario 1 Input: X = ['TP', 'Tutorix'] Output: ['TP', 'Tutorix', 'TPTutorix', 'TutorixTP'] Explanation: When the list contains two strings, say 'TP' and 'Tutorix', it returns two more additional possibilities like 'TPTutorix' and 'TutorixTP'. Scenario 2 Input: X = ['AP', 'BQ', 'CR'] Output: ['AP', 'BQ', 'CR', ... Read More
In this article, we have an array of positive integers of size n. Our task is to calculate the maximum sum of triplet ( ai + aj + ak ) such that 0 sum = 12 3 6 10 => sum = 19 3 4 10 => sum = 17 4 5 10 => sum = 19 2 5 10 => sum = 17 Maximum sum = 19 Finding maximum sum of triplets in an array such than i < j < k and a[i] < a[j] < a[k]Here are the approaches ...

In this article, we are given a mathematical series. Our task is to write a program to find the sum of the series 1 + x/1 + x^2/2 + x^3/3 + .. + x^n/n. This can also be represented as: $$ 1+\displaystyle\sum\limits_{k=1}^n \left(\frac{x^k}{k}\right) $$ This series without starting 1 is known as the Taylor Expansion Series for -ln(1-x) where ln is the natural log. Example Here is an example of calculating the value of the given series: Input: x = 7, n = 4 Output: 747.08 ... Read More
In this article, we are given a mathematical series (1^1 + 2^2 + 3^3 + … + n^n) defined by a number n which defines the nth terms of the series. This series can be represented mathematically as: $$ \displaystyle\sum\limits_{k=1}^n k^k $$ The above series does not have any specific mathematical name but is generally referred to as the power tower series. Below is an example of the power tower series up to n. Example The following example calculates the sum of the given series 1^1 + 2^2 + 3^3 + … ... Read More
In this article, We are given an array arr[] of integers with length n. Our task is to count the number of triplets such that the sum of any two numbers is equal to the third number. Example Here is an example of counting the triplets whose sum of any two numbers equals the third one: Input: arr[]= {1, 2, 2, 3, 4} Output: 4 The explanation of the above example is as follows: Triplet 1: (1, 2, 3) => 1+2=3 Triplet 2: (1, 2, 3) => 1+2=3 Triplet ...

What is Sparse Array?Sparse array is used to determines the dimension of an array in which most of the elements are zero. It can be used for matrix calculation. Characteristics of Sparse Array Following are list of points that defines the characteristics of a sparse array: Most of the elements are zero or null values which means it is unused. Only non-zero elements and their indexes are stored. It is used to save the memory while comparing to normal array calculation. Example The Sparse array of ... Read More
In C++, a superclass serves as a base/parent class. When we create a derived class (or child class) from a superclass, sometimes we have to call the constructor of the base class along with the constructor of the derived class. Unlike Java, there is no reference variable for the superclass. If the constructor is non-parameterized, then it will be called automatically with the derived class, otherwise, we have to put the superclass constructor in the initializer list of the derived class. Constructor Without Arguments It is a default constructor where no argument is passed to it. Here, we create a ... Read More
Dynamic initialization of object refers to initializing the objects at run time i.e., the initial value of an object is to be provided during runtime. Dynamic initialization can be achieved using constructors and passing parameters values to the constructors. This type of initialization is required to initialize the class variables during runtime. Why do we need the dynamic initialization? Dynamic initialization of objects is useful because It utilizes memory efficiently. Various initialization formats can be provided using overloaded constructors. It has the flexibility of using different formats ... Read More
