In this tutorial, we are going to write a program that checks whether the given number is k-rough or k-jagged number or not.The number whose smallest prime factor is greater than or equal to the given k, it is called k-rough or k-jagged number.Let's see the steps to solve the problem.Initialise the numbers n and k.Find all the prime numbers that are factors of n and store them in a vector.Get the first element from the vector and compare it with k to check whether n is k-rough or k-jagged number or not.ExampleLet's see the code.

To plot parallel coordinates, we can take the following Steps −Load dataset iris using Seaborn (Need internet).Pass the loaded data into the parallel_coordinates() method, which will help in parallel plotting.To display the figure, use the show() method.Exampleimport matplotlib.pyplot as plt from pandas.plotting import parallel_coordinates import seaborn as sns plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True data = sns.load_dataset('iris') parallel_coordinates(data, 'species', colormap=plt.get_cmap("Set2")) plt.show()Output
To hide matplotlib.lines.Line2D instance while calling the plot() method, we can take the following steps −Import numpy as np.From matplotlib, import pyplot as plt.Create points for x, i.e., np.linspace(1, 10, 1000)Now plot the line using the plot() method.To hide the instance, use plt.plot(x); (with semi colon)Or, use _ = plt.plot(x).ExampleIn [1]: import numpy as np In [2]: from matplotlib import pyplot as plt In [3]: x = np.linspace(1, 10, 1000) In [4]: plt.plot(x) Out[4]: [] In [5]: plt.plot(x); In [6]: _ = plt.plot(x) In [7]:OutputOut[4]: []
To embed small plots inside subplots, we can take the following Steps −Using subplots() method, create a figure and a set of subplots (fig, ax1).On ax1, plot a line with color red, line width=4, label=”outer plot”.Using add_axes(), add an axis, i.e., ax2 with l, b, h and w values.Plot the same points (Step 2) usins the plot() method, with color green, line width=3, label=”inside plot”.Set the legend on both the plots using the legend() method.To display the figure, use the show() method.Examplefrom matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fig, ax1 = plt.subplots() ax1.plot([1, 4, ...

To change the figuresize using Seaborn factorplot, we can take the following Steps −Load the exercise data using load_dataset() method.Using factorplot() method, change figure size by customising the size and aspect values.To display the figure, use the show() method.Exampleimport seaborn as sns from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True exercise = sns.load_dataset("exercise") sns.factorplot("kind", "pulse", "diet", exercise, kind="point", size=5, aspect=2) plt.show()Output
To set the font size of matplotlib axis legend, we can take the following steps −Create the points for x and y using numpy.Plot x and y using the plot() method with label y=sin(x).Title the plot using the title() method.To set the fontsize, we can override rcParams legend fontsize by value 20.Use the legend() method, and fit the legend at the top-right position.To display the figure, use the show() method.Exampleimport numpy as np from matplotlib import pyplot as plt import matplotlib plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(1, 10, 50) y = np.sin(x) plt.plot(x, y, c="red", lw=7, label="y=sin(x)") ...

ProblemJavaScript function that takes in two arrays, arr1 and arr2 of intervals which are pairwise disjoint and in sorted order.A closed interval [a, b] (with a
ProblemWe are required to write a JavaScript function that takes in an array of integers as the first and the only argument. Our function should return true if and only if we can partition the array into three non-empty parts with equal sums, false otherwise.For example, if the input to the function is −const arr = [3, 3, 6, 5, -2, 2, 5, 1, -9, 4];Then the output should be −const output = true;Output ExplanationBecause, 3 + 3 = 6 = 5 - 2 + 2 + 5 + 1 - 9 + 4ExampleThe code for this will be − Live ...

ProblemWe are required to write a JavaScript function that takes in a binary arr (array that contains only 0 or 1), arr, as the first argument, and a number, num, as the second argument.We can change at most num 0s present in the array to 1s, and our function should return the length of the longest (contiguous) subarray that contains only 1s after making these changes.For example, if the input to the function is −const arr = [1, 1, 1, 0, 0, 0, 1, 1, 1, 1, 0]; const num = 2;Then the output should be −const output = 6;Output ...

ProblemWe are required to write a JavaScript function that takes in an array of strings, arr, as the first and the only argument.Our function is supposed to return an array of all characters that show up in all strings within the array arr (including duplicates).For example, if a character occurs 2 times in all strings but not 3 times, we need to include that character 2 times in the final answer.For example, if the input to the function is −const arr = ['door', 'floor', 'crook'];Then the output should be −const output = ['r', 'o', 'o'];ExampleThe code for this will be ...
