How come import matplotlib.pyplot as plt is not working. This is the code for python import matplotlib.pyplot as plt import numpy as np import random import seaborn as sns

Write a method that computes how often each letter A-Z or a-z occurs in a string. Don't distinguish between upper- and lowercase letters. Return an array of length 26. The ith element contains the number of times that the letter 'a' + i or 'A' + i occurs in the string. The string may contain other characters that you should simply skip.

This question is in java The Sorts.java file is the sorting program we looked at . You can use either method listed in the example when coding. You want to add to the grades.java and calculations.java files so you put the list in numerical order. Write methods to find the median and the range. Have a toString method that prints the ordered list, the number of items in the list, the mean, median and range. Ex List: 20 , 30 , 40 , 75 , 93Number of elements: 5Mean: 51.60Median: 40Range: 73     Grades.java is the main file import java.util.Scanner;public class grades { public static void main(String[] args) {     int n;     calculation c = new calculation();     int array[] = new int[20];     System.out.print("Enter number of grades that are to be entered: ");     Scanner scan = new Scanner(System.in);     n = scan.nextInt();     System.out.println("Enter the grades: ");     for(int i=0; i<n; i++)     {         array[i] = scan.nextInt();         if(array[i] < 0)         {…

Given a string, write a method that returns the number of occurrences of substrings "baba" or "mama" in the input string recursively. They may overlap. Do not use any loops within your code. Do not use any regular expressions and methods such as matches, split, replaceAll. "Maa mana, Test case 1: countBabaMama ("aba babaa amama ma") 2 Test case 2: countBabaMama ("bababamamama") 4

I need help finding out what to put in the: encryptedArray[index] = encrypt(messageArray);//pass something to encrypt from the array System.out.print(messageArray);//print encrypted version portion of the coding as well as how to call the "encryptAll" method

I need help with this Java problem to output as it's explained in this image below:   Ex: If input is 84 72 19 61 19 84   then output is: List after inserting 84:  84  List after inserting 72:  72 84  List after inserting 19:  19 72 84  List after inserting 61:  19 61 72 84  List after removing 19:  61 72 84  List after removing 84:  61 72     LabProgram.java code below (Needs editing) import java.util.Scanner; import java.io.PrintWriter;   public class LabProgram { // Prints the SortedNumberList's contents, in order from head to tail public static void printList(SortedNumberList list) { Node node = list.head; while (null != node) { System.out.print(node.getData() + " "); node = node.getNext(); } System.out.println(); }   public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String inputLine;   // Read the line of input numbers inputLine = scnr.nextLine();   // Split on space character String[] terms = inputLine.split(" ");   // Insert each value and show the…
