In this problem, we are given an array divisors[] consisting of N integers which are the divisors of a number Num. Our task is to find the number from its divisors.The divisor array does not include 1 and the number.Let’s take an example to understand the problem, Inputdivisors[] = {3, 25, 5, 15}Output75ExplanationThe number 75 has divisors {3, 25, 5, 15}Solution ApproachTo solve the problem, we need to find the number Num using the smallest and largest divisors of the number.Num = smallest * largestFor this, we need to sort the array divisors[] and then find the product of elements ...

Using plt.xticks, we can change the X-axis scale.StepsUsing plt.plot() method, we can create a line with two lists that are passed in its argument.Add text to the axes. Add the text *s* to the axes at location *x*, *y* in data coordinates, using plt.text() method, where the font size can be customized by changing the font-size value.Using xticks method, get or set the current tick locations and labels of the X-axis.To show the figure, use plt.show() method.Exampleimport matplotlib.pyplot as plt plt.plot([1, 2, 4], [1, 2, 4]) plt.text(2, 3, "y=x", color='red', fontsize=20) plt.xticks([1, 2, 3, 4, 5])   ...
