please write the python code to implement without error for this problem. I am stuck. 3. You will need to import the function random from the module numpy.random. Here wewill make 4 sub-plots in a 2 × 2 arrangement. Use linspace (-1,1,201) appropriately,so we have 100 equally spaced intervals from -1 to 1.a) In the upper left, plot a histogram of 500 random numbers distributed between -1an 1 using random. Note that if you have an array xr you can make a new array yr thathas 1 added to each value in xr by simply executing yr= xr + 1.b) In the upper right quadrant, plot 2 functions on the same set of axes, y(t) = t² andy(t) = t³ — t1c) In the lower left, plot 100 random points with −1 < x < 1 and −1 < y < 1. Makesure you use dots to represent the points and that they are not joined by lines!d) For the lower right, plot the points (x(t), y(t)), where x(t) = tcos(10t) and y(t)t sin(10t).e) Place the title Data Visualization over the entire set of 4 sub-plots.=

Import Libraries:The code imports numpy (as np) and matplotlib.pyplot (as plt). These libraries are…

A left rotation operation on an array of size n shifts each of the array's elements 1 unit to the left. Given an integer, d, rotate the array that many steps left and return the result. Example:d=2arr=[1,2,3,4,5] After 2 rotations, arr'=[3,4,5,1,2]. Function Description: Complete the rotateLeft function in the editor below. rotateLeft has the following parameters: 1. int d: the amount to rotate by 2. int arr[n]: the array to rotate Returns 1. int[n]: the rotated array Input Format: The first line contains two space-separated integers that denote n, the number of integers, and d, the number of left rotations to perform.The second line contains n space-separated integers that describe arr[]. Constraints: 1. 1<=n<=10^5 2. 1<=d<=n 3. 1<=a[i]<=10^6
In a one-dimensional array, one-year average daily temperature information of the city of Karabük is kept. The average daily temperature information is between -25 and 35 degrees. Accordingly, write a function that takes this array as a parameter and finds the number of temperatures between [-25, -10), [-10, 5), [5, 20) and [20, 35] values and prints it to the screen in that order. Sample Output ( Example Output ): [-25, -10) : 13 [-10, 5) : 93 [5, 20) : 117 [20, 35] : 142
Now, write another function that prints the values of any array in reverse order. (The function should not change the original array). As an example, if a [] = {1, 2, 3, 4, 5}; The function would print the values in reverse as: 5, 4, 3, 2, 1
Write a program that takes 20 elements of array from user at run time. And also Find maximum element of array and swap it with last element of array. Display before and after swapping array.
Create a 4x3 array of letters from a through l and call it array1. Copy the array and call it array2, then reshape array2 to a 6x2 array. Create another copy of the array, called array3, and flatten it into a one-dimensional array. Print all three arrays.
Write a program for the following information: Year has 365 days. You create array for temperature of each day in a year. Assign random temp values range of 30-110. Using a function Search in the array do you have 100 degree and what days. Print how many days and what days. Also print the Temp array in nice format in a function. Sample output
You are supposed to build a system for currency conversion into Pakistani rupees, US dollars, dirhams and rayals. Write a program that asks 10 amounts and corresponding currency in arrays. Program shall then ask which unit in which user wants to convert each amount into and store it in a new array. The program should prompt invalid currency when something other than given currencies is entered as the currency to be converted from or currency to be converted to. It shall be able to convert any of these four currencies into each other. Program shall than store converted amounts in a new arrays and display all record the original amounts along with their currencies and converted amount with new currency. I want answer in c++ language can you make it easy for me ? :)

Getting the Concatenated Number In the code editor, you will see that there's a globally declared integer array named, dataset. Additionally, there's a function declaration for the function getConcatenatedNumber(int n). Your task is to define the getConcatenatedNumber function. This will accept an integer n and will perform some operations on the global array. If the passed integer n is an even number, you need to concatenate all the integers located in the even indices (special case: 0 index is considered as even here). If the passed integer n is an odd number, you need to concatenate all integers located in the odd indices. Since 0 is neither odd or even, you need to concatenate all the integers in the array if n is 0. Afterwards, you need to add the inputted integer n three times to the concatenated number and return the result. In the main(), ask the user to input the value of n, call the function getConcatenatedNumber and pass the value of n, and then print the result. SAMPLE:…

Write a program that will read the monthly salary of 10 employees and then calculates the income tax (i.e, 10% of the salary) and net salary. Hence you have to declare an array salary[10][3]. Your program should have 4 functions. The first function will be used to read monthly salary of 10 employees and put it in the first column of the array. The second function will be used to calculate the income tax for each employee and then store it in the second column of the array. The third function will be used to calculate the net salary of each employee and store it in the third column of the array. Finally, the fourth function will be used to display the gross salary, income tax and net salary for each employee. You must pass the array as reference in each function you used.
