Each line of the square consists of a wrapping sequence of integers increasing from min and max. The first line begins with min, the second line begins with min + 1, and so on. When the sequence in any line reaches max, it wraps around back to min. You may assume that min is less than or equal to max.

Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…
x = 3 + numbers[3]++; System.out.println(x); QUESTION 2: Class Rectangle has two data members, length (type of float) and width (type of float). The class Rectangle also has the following: //mutator methods void setlength (float len) } //B. length = len; H accessor methods float getLength() I return length; The following statement creates an array of Rectangle with size 2: Rectangle[] arrayRectangle= new Rectangle[2]; Is it correct if executing the following statements? What is the output? If it is not correct, write the correct one arrayRectangle. setLength (12.59); System.out.printin[rectangle Set.getLength()); arrayRectangle[1].setLength(4.15); System.out.println(arrayRectangle[1].getLength()): QUESTION 3: Use the following int array int[] numbers = { 42, 28, 36, 72, 17, 25, 81, 65, 23, 58} -Open file data.txt to write. to write the values of the array numbers to the file with the y numbers to get the values
PrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output…

Recipe Program - Java ONLYI am looking to create a program that is a recipe holder. It needs to include at a minimum: At least 1 loop An Array or ArrayList At least 3 Java classes Use of methods The program would allow the user to (as part of a menu selection): Add a recipe Include ingredient list Instructions List all recipes that are in the program (array) Display a single recipe Search Recipes (option to view recipe selected) For example, searching for peanut butter cookie would bring up the recipe or multiple if the same name. The user could then select one of them to view the recipe. Search Recipes with a single ingredient (option to view recipe selected) For example: search for coconut and it would bring up coconut cream pie and German chocolate cake. The user could then select one of them to view the recipe. Close application Also need the program in a UML diagram.
strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down). Find all strobogrammatic numbers that are of length = n.

Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);
JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT #2 so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #8. 8. Sum of Numbers in a String (page 610) Write a program that asks the user to enter a series of numbers separated by commas. Here are two examples of valid input: 7,9,10,2,18,6 8.777,10.9,11,2.2,-18,6 The program should calculate and display the sum of all the numbers. Input Validation 1. Make sure the string only contains numbers and commas (valid symbols are '0'-'9', '-', '.', and ','). 2. If the string is empty, a messages should be displayed, saying that the string is empty. Test Case 1 Enter a series of numbers separated only by commas or type QUIT to exit:\n7,9,10,2,18,6ENTERThe sum of those numbers is 52.00\nEnter a series of numbers separated only by commas or type QUIT to exit:\nENTEREmpty string.\nEnter a series of numbers separated only by…
