- JAVASCRIPT SOLUTION PLEASE You are going to be given a word. Your job is to return the middle character of the word. If the word's length is odd, return the middle character. If the word's length is even, return the middle 2 characters.arrow_forwardChange this code to show strings that help you cast twelve dice. They should be shown one at a time like this:The first one was A. The second one was B. Afterward, the sum should be shown on a different line.arrow_forwardUsing a Sentinel Value to Control a while Loop Summary In this lab, you write a while loop that uses a sentinel value to control a loop in a Java program that has been provided. You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the file named MovieGuide.java is open. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop to calculate the average star rating. Execute the program by clicking Run. Input the following: 0, 3, 4, 4, 1, 1, 2, -1 Check that the average…arrow_forward
- In PYTHON Using one of the loop construct draw:- Twenty horizontal lines- Each line of length 150 units(or pixels)- All lines aligned at the same left horizontal margin- Lines 10 units apart each other Note- The first line and all lines in odd positions(e.g. 1, 3, 5, etc.) should besolid lines- The second line and all lines in even positions(e.g. 2, 4, 6, etc.)should be dashed lines - - Set the length of solid segment to 10 units - - Set the length of the non-visible segment to 5 units Assumption- Use of Turtle libraryarrow_forwardMULTIPLE CHOICE -The answer is one of the options below please solve carefully and circle the correct option Please write clear .arrow_forwardPrimeAA.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…arrow_forward
- Lab Goal : This lab was designed to teach you how to use a while loop. Lab Description (JAVA PROGRAMMING): Remove all occurrences of the removal string from the original string. Each time you take out the removal string you must also remove the letter that preceded the removal string. After you remove a string and its leading character, you must check to see if any more occurrences of the removal string exist. Sample Data : xR-MxR-MHelloxR-M R-M sxsssxssxsxssexssxsesss xs fuxqwexqwertyxqwexqwe Sample Output : xR-MxR-MHelloxR-M - String to remove R-M Hello sxsssxssxsxssexssxsesss - String to remove xs sesss fuxqwexqwertyxqwexqwertyrtyxqwertyrtyn - String to remove qwerty fun dogdogcatddodogdogdoggog - String to remove dog catgog algorithm help use indexOf to look for more removals while you have more removals { take out the current removal using substring use indexOf to look for more removals } I need help with assignment: "String Cleaner" StringRemover.js: //(c) A+…arrow_forwardThe text presented the Sierpinski triangle fractal. Inthis exercise, you will write a program to display another fractal, called the Kochsnowflake, named after a famous Swedish mathematician. A Koch snowflake iscreated as follows:1. Begin with an equilateral triangle, which is considered to be the Koch fractalof order (or level) 0, as shown in Figure a.2. Divide each line in the shape into three equal line segments and draw an outwardequilateral triangle with the middle line segment as the base to create aKoch fractal of order 1, as shown in Figure b.3. Repeat Step 2 to create a Koch fractal of order 2, 3, . . . , and so on, as shownin Figures c and d.arrow_forwardDiscrete Mathematics: Assignment details: Replace all the 0 (Zero) digits in your ID by 4. Example: If your ID is 38104680, it becomes 38144684 Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table; Letter Replace by Digit Example Digit A 1st 3 B 2nd 8 C 3rd 1 D 4th 4 E 5th 4 F 6th 6 After substitution your expression will be similar to this (( 3 + 8) / 1) * ((4-4)/6)-2). Draw a rooted tree that represents your expression. What is the prefix form of this expression. 3.What is the value of the prefix expression obtained in step 2 above?arrow_forward
