A positive whole number n > 2 is prime if no number between 2 and n (inclusive) evenly divides n. Write a program that accepts a value of n as input and determines if the value is prime. If n is not prime, your program should quit as soon as it finds a value that evenly divides n.

- Description A mathmatician Goldbach's conjecture: any even number(larger than 2) can divide into two prime number’s sum.But some even numbers can divide into many pairs of two prime numbers’ sum. Example:10 =3+7, 10=5+5, 10 can divide into two pairs of two prime number. Input Input consist a positive even number n(4<=n<=32766). Output Print the value of how many pairs are this even number can be divided into. Sample Input 1 1234 Sample Output 1 25Problem specification: There is a grid of NXN squares. We can easily determines how many different rectangles (squares are excluded) there are in the grid. For example, in a 3X3 grid, you can find 22 different rectangles, marked as the green rectangles. You can see that we did not count the red ones as they are squares. In this assignment, you will write a Java program that takes the value of N as input and determines the total area of all the rectangles in the grid. Assume that the smallest squares in the grid have length 1. So a 3X2 rectangle will have an area of 6. For example, the total area of all the rectangles in the 3X3 grid is 66.…Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.
- A prime number is called a Mersenne prime if it can be writtenin the form 2p - 1 for some positive integer p. Write a program that findsall Mersenne primes with p ≤100 and displays the output as shown below.(Hint: You have to use BigInteger to store the number because it is too big tobe stored in long. Your program may take several hours to run.) p 2^p – 1---------------------2 33 75 31...: In the classic problem FizzBuzz, you are told to print the numbers from 1 to n. However,when the number is divisible by 3, print "Fizz''. When it is divisible by 5, print "Buzz''. When it isdivisible by 3 and 5, print"FizzBuzz''. In this problem, you are asked to do this in a multithreaded way.Implement a multithreaded version of FizzBuzz with four threads. One thread checks for divisibilityof 3 and prints"Fizz''. Another thread is responsible for divisibility of 5 and prints"Buzz''. A third threadis responsible for divisibility of 3 and 5 and prints "FizzBuzz''. A fourth thread does the numbers./*code Kth Largest Factor A positive integer d is said to be a factor of another positive integer N if when N is divided by d, the remainder obtained is zero. For example, for number 12, there are 6 factors 1, 2, 3, 4, 6, 12. Every positive integer k has at least two factors, 1 and the number k itself.Given two positive integers N and k, write a program to print the kth largest factor of N. Input Format: The input is a comma-separated list of positive integer pairs (N, k). Output Format: The kth highest factor of N. If N does not have k factors, the output should be 1. Constraints: 1<N<10000000000 1<k<600. You can assume that N will have no prime factors which are larger than 13..
- use JAVA to write the code. : Euclid’s algorithm for finding the greatest common divisor (gdc) of two numbers The algorithm: given two numbers, n1 and n2: Divide n1 by n2 and let r be the remainder. If the remainder r is 0, the algorithm is finished and the answer is n2. (If the remainder is 1, the numbers are mutually prime and we are done-see below.) Set n1 to the value of n2, set n2 to the value of r, and go back to step 1. Entering 0 for one of the values is bad. It should work for the other value, but you have to figure out which is OK and which is bad. Catch this problem as it happens and make the user enter another value until they enter an acceptable one. Give an appropriate error message if this happens.Exercise III: Catalan numbers For n e N, denote by c, to be the number of ways to form a "mountain range" with n upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance: for n = 1, only UD is allowed, so c = 1; • for n = 2, only UUDD and UDUD are allowed, so c2 = 2. 1. Check that c3 = 5 by writing down or drawing all possible options. 2. Consider the power series +00 g(x) = 2 n=0 (by definition co = 1) called the generating function of the sequence (en). Justify that cn < 4" for each n, and deduce that the radius of convergence of g is at least 1/4. 3. It can be show that for r E (-1/4, 1/4), g(x) = 1+ xg(r)? and therefore 1- VI 4.x g(x) = 2.x Use this formula and the known power series of V1+ x to write the first terms of the power series expansion of g, in the form g(x) = co + c1x + c2x2 + C3x + c4x* + ·.. Show how you obtain a few terms, but you do not need to show all computations and you can use a calculator for fractions. Check that you recover co,…1. Write a program called NumberGuess to play the number guessing game. The program shall generate a random number between 0 and 99. The player inputs his/her guess, and the program shall respond with "Try higher", "Try lower" or "You got it in n trials" accordingly.
- Q1: Write a program that reads a set of N integers. Then, the program finds and outputs the sum of the even values and the sum of the odd values of them. For example: if the value entered for N=5, and the five integers are 3, 6, 2, 9, 7. Then the sum of even values (6+2 = 8), and the sum of odd values (3+9+7 = 19) Q2: Write a program that reads some numbers until it reaches a specific value (assume -1 is a stop value in this case). The program should find and outputs the average of all of the numbers (between 10...40) except the stop value (-1). For example: If the numbers look like: 12 5 30 48 -1. Then, the average of the numbers: (12+30)/2 = 21.There are five errors in this code. Correct the errors and make the code work. Explain what are the errors found. import java.util.Scanner; //Testing.java //Displays running total of numbers in lines of standard //input correct to two decimal places. //Uses an out of range number (100) to quit. public class TWODPS{ public static void main (String [] args) { Scanner input new Scanner (System.in); double total=0; boolean flag=true; System.out.println ("Use an out of range entry 100 to quit."); while (flag) { System.out.println ("Enter a number on a line:"); double d = input.nextDouble (); if (outofRange (d) ) { flag=false; else{ dispTwoDPs ("The number value is: ",d); total = total + d; dispTwoDPs ("The total is: ",total); System.out.println (); System.out.println ("Next."); } //end of else }//end of while System.out.println ("You quit."); }//end of main static boolean outOfRange (double d) { if (d>-100) return true; if (d>100) return true; return false; }Problem 7: Guess the price of the car!? You will implement a variant of the number guessing game we played in lecture. In this variant, you will ask the user to guess the price of a $42,500 car. Let's assume that the player knows the price of the car is rounded to the nearest $500. If a player's guess is not exactly correct, your program will tell them they are either too high or too low. The player will get as many guesses as they need to guess the price of the $42,500 car. However they will only win the game if they used 5 or fewer guesses. Here are two examples of how the program should work for both cases: Guess the price and win the prize! Enter your guess:50000 Too high! Enter your guess:40000 Too low! Enter your guess:45000 Too high! Enter your guess:42500 You won the car! Guess the price and win the prize! Enter your guess:46000 Too high! Enter your guess:45000 Too high! Enter your guess:44000 Too high! Enter your guess:43000 Too high! Enter your guess:42000 Too low! Enter your…
