One way to solve this problem is to use a doubly nested loop. The outer loop can iterate from 3 to 100 while the inner loop checks to see if the counter value for the outer loop is prime. One way to see if number n is prime is to loop from 2 to n 21 and if any of these numbers evenly divides n, then n cannot be prime. If none of the values from 2 to n 21 evenly divides n, then n must be prime. (Note that there are several easy ways to make this

- JAVA A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. A divisor of an integer x is an integer that can divide x evenly. Take an integer n as input from the keyboard, print true if n is a perfect number, otherwise, print false. You do not need to print any explanation, just print true or false. Use a for loop to generate the divisors. Example 1: Input: num = 28 Output: true Explanation: 28 = 1 + 2 + 4 + 7 + 14 1, 2, 4, 7, and 14 are all divisors of 28. Example 2: Input: num = 6 Output: true Example 3: Input: num = 496 Output: true Example 4: Input: num = 8128 Output: true Example 5: Input: num = 2 Output: falsearrow_forwardWrite a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example output for userNum = 40:20 10 5 2 1 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 40, then with userNum = 2, then with userNum = 0, then with userNum = -1. See "How to Use zyBooks".Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message.arrow_forwardWrite a program that reads in numbers from the user and outputs the information specified below. Part One: Get Valid Input Read in two integers from the user: a lower end of a range and an upper end of a range. Check if the numbers are valid (lower cannot be greater than upper). If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values. Part Two: Calculate the Sum Use a loop to calculate the sum of all values from lower (inclusive) to upper (inclusive). Output the sum to the user. Part Three: Analyze the Sum Determine if the sum is even or odd. Determine if the sum is positive, negative, or zero. Output this information to the user. Part Four: Calculate the Average Calculate the average of all numbers in the range from lower (inclusive) to upper (inclusive). Style and Additional Coding Requirements code should compile properly space and indent your code follow Java naming conventions for variables (lower camel case with no…arrow_forward

In each loop iteration, divide user_num by 2, then print user_num.Sample output with input: 2010.0 5.0 2.5 1.25 0.625 while(userNum > 1) {userNum = userNum / 2;System.out.print(userNum + " ");}arrow_forward
- Write a loop of your choice that continues to read an integer x as long as x not divisible by 5 and 3. Complete the missing code in the space provided below. { int x=1; ............ }arrow_forwardin python "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings. For each match, add one point to user_score. Upon a mismatch, end the game.Sample output with inputs: 'RRGBRYYBGY' 'RRGBBRYBGY'User score: 4 user_score = 0 simon_pattern = input() user_pattern = input() ''' Your solution goes here ''' print('User score:', user_score)arrow_forwardWrite a program that asks a user to input the height of triangle and draw a triangle that has the following pattern. Use nested loops for this problem. If the user enter height as 4 Then the triangle output is 1 1 2 1 2 3 1 2 3 4 We make the following assumptions • There is no space between the margin and first number in each row • There could be a space after the last number on every line • There is pne space between numbers on every line • There maybe a newline at the end of last line There is one test-case to check your code, there are two hidden testcases that tests correctness of your code 376584 2469arrow_forward
