Java Code 1. FizzBuzz by CodeChum Admin Let’s play a game of FizzBuzz! It’s quite the same with your childhood "PopCorn" game, but with a little bit of twist to align it with programming. Are you ready? Instructions: Input a positive integer in one line. This will serve as the ending point of your loop. Loop from 1 to the ending point (inclusive) and perform the following statements: If the number is only divisible by 3, print "Fizz" If the number is only divisible by 5, print "Buzz" If the number is divisible by both 3 and 5, print "FizzBuzz" If nothing is true in the previous conditions, skip the number Instructions Scan a positive integer n and store it in a variable. Create a counter variable with a value of 1 and create a loop from counter to n. Print "Fizz" if the counter in the loop is divisible by 3, "Buzz" if the counter is divisible by 5, "FizzBuzz" if it is both divisible by 3 and 5. Skip the iteration if it is not divisible by 3 or by 5. Input A line containing…
• Write a program that asks the user to enter the size of a triangle (an integer from 1 to 10) • Display the triangle by writing lines of asterisks • The first line will have one asterisk, the next two, and so on, with each line having one more asterisk than the last line up to the number entered by the user. • On the following line, write one fewer asterisk and continue decreasing the number of asterisks by 1 for each successive line until only one asterisk is displayed. (Hint: Use nested for loops; the outside loop controls the number of lines to write, and the inside loop controls the number of asterisks to display on a line.) • For example, if the user enters 3, the output would be: Input Data: • An integer between 1 to 10 Set up an input validation loop to ensure the entered data is within range • As long as the entered data is not within range, the user is to be prompted repeatedly until the entered data is within range; at that point, then the valid input data is to be used to…

Description Dot Product Task: Write a program that outputs the dot product of two given vectors. Your program should read the vectors from command line arguments, convert them to integers, output the vectors, and finally compute and output the resulting dot product. Let V and U be two vectors, where |V| we run the program as $ python dotproduct.py 156724 then the two vectors are V = [1, 5, 6] U = [7, 2, 4] and their dot product is calculated by V • U = (1 × 7) + (5 * 2) + (6 × 4) Example $ python dotproduct.py 1 23321 V = { 1, 2, 3 } U = {3, 2, 1 } V. U = 10 = ||U|= = 3 (the size of both vectors will always be 3). If
C level program 1. Write a program that takes an integer n as input (from Keyboard) and compute and display (a) The sum of digits. (b) The integer with digits reversed, and multiplied by 3. For example, if the input is 4318, then in part (a), you'll display integer 4318, and sum of digits 4 + 3 + 1 + 8 = 16; and in part (b), you'll compute and display 8134 and also 24402, which is 4318 * 3. (c) Test your program with 3 integers: 4318, 401, and an integer of 5 digits of your choice. Show and explain source code and show output

Using introduction to Python You have been asked to write an application that automatically grades a quiz. The quiz has 15 multiple-choice questions. The correct answers are: 1.A, 2.C, 3.A, 4.B, 5.B, 6.D, 7.D, 8.A, 9.C, 10.A, 11.B, 12.C, 13.D, 14.C, 15.B The program will start by creating a list holding the quiz answers key shown above. It will then prompt the user for the student name and their answers file and read them into a separate list. It will finally compare the key vs. answers lists to calculate & display: Number of correct answersNumber of incorrect answersQuestions incorrectly answered.Whether the student has passed or failed the quizA student must correctly answer 11 out of 15 questions to pass.The user can grade as many students as they wish. Notes The file containing the student’s answers is organized as 15 lines. Each line contains the answer to the corresponding question. The responses are single character strings, from A to D, uppercase. Must use functional…
