Centered Octagonal Number
The problem statement includes printing the N-th centered octagonal number for some positive integer N, which will be given by the user. A centered octagonal number is a type of number which can be represented in a pattern of figures. Every centered octagonal number can be represented as a dot in the centre surrounded by the successive layers of an Octagon. An octagon is a type of polygon in geometry which has 8 sides in it. The successive layers of an octagon means that the first layer surrounding the dot in the centre will be an octagon, the second ...
Read MoreCentered Octadecagonal Number
The problem includes to print the N-th centered octadecagonal number, where N will be given as an input. A centered octadecagonal number is a type of figurative number which is represented as a dot in the centre surrounded by the successive layers of the octadecagon. An octadecagon is a polygon with 18 sides in it. The successive layers of the octadecagon are the first layer will be 18-sided polygon, the next will be 36-sided polygon and so on. The numbers can be better explained with the help of figures. The first number is represented as a dot in the ...
Read MoreCentered nonadecagonal number
The problem statement includes printing of the N-th centered nonadecagonal number for any positive value of N. A centered nonadecagonal numbers are numbers which are represented in a particular pattern of figure. This number can be represented in a figure as a dot in the centre surrounded by the successive layers of the nonadecagon. A nonadecagon is a type of polygon in mathematics which has 19 sides in it. The successive layers of the nonadecagon suggests that the first layer surrounding the dot in the centre will be 19 sided polygon followed by 38 sided polygon and so ...
Read MoreCentered dodecahedral number
The problem statement says to print the N-th centered dodecahedral number for any positive value of N which will be the user input. A centered dodecahedral number is a number that can be represented in a particular pattern of figure. A dodecahedron is a three-dimensional figure in mathematics which has 12 flat faces. And a centered dodecahedral number is a number which can be represented in the form of a figure with a dot in the centre surrounded by the successive layers of the dodecahedron (12 faced 3-d structure). The successive layers of the dodecahedron says the first layer will ...
Read MoreCentered cube number
The problem statement includes printing the N-th centered cube number for some positive value of N, which will be the user input. A centered cube number is the number of points in a three-dimensional pattern created by a point surrounded by concentric cubical layers of points, with i^2 points on the square faces of the ith layer. It is equivalently the number of points in a body-centered cubic pattern within the cube with n + 1 points along each of its edges. You can refer to wikipedia for figurative representation of the centered cube number which will help in better ...
Read MoreCreate linked list from a given array in C++ Program
In this tutorial, we are going to learn how to create a linked list from the given array.Let's see the steps to solve the problem.Initialize the array with dummy data.Write the struct node.Iterate over the array.Create a new node with the data.Insert the new node into the linked list.Print the linked list.ExampleLet's see the code.#include using namespace std; struct Node { int data; Node* next; }; struct Node* newNode(int data) { Node* node = new Node; node->data = data; node->next = NULL; return node; } void insertNewNode(Node** root, int data) { Node* ...
Read MoreDifferences between Procedural and Object Oriented Programming
Both Procedural Programming and Object Oriented Programming are high-level languages in programming world and are widely used in the development of applications. On the basis of nature of developing the code, both languages have different approaches on basis of which both are differentiate from each other. In this article, we will discuss the important differences between procedural oriented programming and object oriented programming. But before going into the differences, let's start with some basics. What is Procedural Programming? Procedural Programming is a programming language that follows a step-by-step approach to break down a task into a collection of variables ...
Read MoreHow to create a vector with repeated values in R?
There are two methods to create a vector with repeated values in R but both of them have different approaches, first one is by repeating each element of the vector and the second repeats the elements by a specified number of times. Both of these methods use rep function to create the vectors.ExampleConsider the below examples −> x1 x1 [1] 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 [39] 4 ...
Read MoreHow to clear the memory completely of all Matplotlib plots?
Using the following methods, we can clear the memory occupied by Matplotlib plots.plt.figure() - Create a new figure or activate an existing figure.plt.figure().close() - Close a figure window.close() by itself closes the current figureclose(h), where h is a Figure instance, closes that figureclose(num) closes the figure number, numclose(name), where name is a string, closes figure with that labelclose('all') closes all the figure windowsplt.figure().clear() - It is the same as clf.plt.cla() - Clear the current axes.plt.clf() - Clear the current figure.Examplefrom matplotlib import pyplot as plt fig = plt.figure() plt.figure().clear() plt.close() plt.cla() plt.clf()OutputWhen we execute the code, it will clear all the plots from ...
Read MorePlot a bar using matplotlib using a dictionary
First, we can define our dictionary and then, convert that dictionary into keys and values. Finally, we can use the data to plot a bar chart.StepsCreate a dictionary, i.e., data, where milk and water are the keys.Get the list of keys of the dictionary.Get the list of values of the dictionary.Plot the bar using plt.bar().Using plt.show(), show the figure.Exampleimport matplotlib.pyplot as plt data = {'milk': 60, 'water': 10} names = list(data.keys()) values = list(data.values()) plt.bar(range(len(data)), values, tick_label=names) plt.show()Output
