mand-line argument n and will printsan n-by-n pattern like the one below. Make sure to include two space characters between each character.  example: input= 4 output = +

Declare an integer array named countingNumbers and fill it with the integers 1 through 10 consecutively. Do this all in one statement. (Be sure to use the same spacing as NetBeans does for this statement.)   this is needed in Java

Simple Javascript only:  Convert a Hexadecimal array of numbers into decimal values. The decimal values should be treated as ASCII character codes and converted into characters. Return a string of those characters. See the MDN docs for `String.fromCharCode()` method for how to convert character codes into ASCII characters. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/fromCharCode Examples: hexadecimalToString(['0x004a']) => 74 => "J" hexadecimalToString(['0x0041', '0x0042', '0x0043']) => 65, 66, 67 => "ABC" hexadecimalToString(['0x0048', '0x0065', '0x0078', '0x0061']) => 72, 101, 120, 97 => "Hexa".   function hexadecimalToString(hexadecimalChars){ }

In Java Assume code that has imported Scanner and instantiated it for keyboard input as stdln. Wtire a code fragment that does the following: 1. Uses a for loop to fill each array element with the square root of that elements index value

Using python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered  The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive.  Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations.   Remember to validate the input and display an error message if the user inputs invalid data.  Documentation and the screenshot(s) of the results.  Example:  1  2  3 4  5  6 7  8  9 the result will be :  1  4  7 2  5  8 3  6  9

Create the following program to demonstrate working with arrays in java. Your company pays its sales staff on a commission basis. Each employee receives $500 per week plus 6.5% of their sales. For example, a salesperson who sells $10,000 worth of products will get a salary of 500 + (10000 * .065) or $1150 for that week. You are given the task of creating a program to allow a manager to enter in the sales for 10 employees. (Store them in an array of course.) Then it should display the 10 sales amounts, the 10 salaries for this pay period, and the average salary. (Hint: There are a couple ways to approach this one, here are two ideas: (1) You could create a second array for the salaries and load it at the same time as you gather and store the sales, then loop through the salaries one to find the average, and then you have all the pieces to print. (2) Another solution would be to take in the sales, and then calculate the salaries on the print (which means you don't have to store them in a…

in java  Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. If the first element is less than the last element, then assign Boolean firstSmaller with true. Otherwise, assign firstSmaller with false. Ex: If the input is: 5 40 22 41 84 77 then the output is: First element is less than last element 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20     import java.util.Scanner;   public class UserTracker { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; int[] userCounts; inti; booleanfirstSmaller;   numVals=scnr.nextInt();   userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); }   /* Your code goes here */    if (firstSmaller) {            System.out.println("First element is less than last element");        }        else {            System.out.println("First element is not less…

Write a program that can be used to gather statistical data about the number of movies college students see in a month. The program should perform the following steps: Ask the user how many students were surveyed. An array of integers with this many elements should then be dynamically allocated.. Allow the user to enter the number of movies each student saw into the array. Calculate and display the total and average of the values entered. Input validation: Do not accept negative numbers for input.
