: 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.
Write a program that allows the user to enter a number between 1 and 1000. If the number is invalid, provide an error message and allow the user to try again until he enters a valid value.
Once you have a valid number, use it to determine and print the following information:
*Note that in the list of factor pairs, you should not include duplicates.
program in python
Number squared
Number cubed
Number Type: Even composite numberOdd or Even Prime (Exactly 2 factors) or Composite (More than 2 factors)
Whether the number is a perfect square: No (6 does not have an integer square root like 4 or 9)
Square Root: (Print this line only if the number is perfect square)
List of factors that exclude duplicates and are printed horizontally on a single lineFactors: (1, 12) (2, 6) (3, 4) (4, 3) (6, 2) (12, 1) should not be included
If you add up all the digits in 468, you get 4 + 6 + 8 = 18. The square and cube of 468 are 219024 and 102503232, respectively. Interestingly, if you add up the digits of the square or cube, you get 18 again. Are there other integers that share this property? Write a program that lists all positive integers k less than 1000 such that the three numbers k, k2, and k3 have digits that add up to the same number.

- please code in python You are probably familiar with the famous Fibonacci sequence of numbers, which begins like this: 1, 1, 2, 3, 5, 8, 13, 21... We'll index from 0, so the 0th and 1st numbers are both 1. The 2nd Fibonacci number is found by summing the 0th and 1st: 1 + 1 = 2. The 3rd is found by summing the 1st and 2nd: 1 + 2 = 3. After this point, each Fibonacci number is found by summing the previous two numbers. You are to write a recursive function to compute the nth Fibonacci number. This means that your function will call itself and will NOT include explicit loops. Hint: Your function should include a line that looks a lot like the mathematical definition of the nth Fibonacci number. Another Hint: It's possible for a recursive function to call itself more than once. Example: print(Fibonacci(1)) 1arrow_forwardYou are given an integer, N.

- You have been hired by a local organic sod company to write coverage calculator for their website. Organic sod is cut into rectangles 9 square foot in area for lawn installation. Your program will prompt the customer for the length and the width of a rectangular area being covered with sod. Implement the following "pseudocode" to obtain the number of pieces to order. • Compute the area of the rectangle to be covered • Divide the area by 9 • Convert the result to an integer and then add 1 Below is a sample run with Python output in blue and user input in black. Enter length:200 Enter width:40 You should order 889 pieces.arrow_forwardWATERSORT PROGRAM - JAVA •The aim of Part 2 is to set up the puzzle for the player to solve in Part 3. IMPORTANT NOTE: We are not going to start with 2 empty bottles, but rather with 8 empty slots spread over the 5 bottles as explained in the intro video. Start with 5 empty bottles. Use a random number generator to fill bottles one slot at a time with the colours while keeping 8 slots empty – there is a total of 5*4 = 20 slots – so if we will 12 slots, 8 are free. •Advantage: Easy to create a puzzle with a good mix •Disadvantage: With more colours and bottles and only 2 open bottles for more advanced versions of the game, the result might not be solvable. Start with three sorted bottles. In the strategy the idea is to load three bottles with uniform colour and then move ink around for a number of moves until the bottles are mixed up. •Advantage: Result is always solvable since the bottles are created in a reversed-game strategy. •Disadvantage: It is hard to develop an algorithm which…arrow_forward1.Given a positive integer, N, the ’3N+1’ sequence starting from N is defined as follows:If N is an even number, then divide N by two to get a new value for NIf N is an odd number, then multiply N by 3 and add 1 to get a new value for N.Continue to generate numbers in this way until N becomes equal to 1For example, starting from N = 3 the complete ’3N+1’ sequence would be:3, 10, 5, 16, 8, 4, 2, 1Write c++ code to ask the user to enter a positive integer (N) in the main() function. Write a function sequence()that receives the integer value N and display the ‘3N+1’ sequence starting from the integer value that wasreceived (entered by the user). The function must also count and return the numbers that the sequenceconsists of. The returned value must be displayed from the main() function.arrow_forward
- As the algorithm performs division of numbers with high precision, it is very common to see really big numbers after the period (for example: 1200.2300001), which is not desirable because of several reasons: may cause confusion to some users when they see such big numbers; uses more memory to store a bigger number; it just does not make sense to display currency number in this format. For this reason, you are going to implement a utility function to format any number into the appropriate currency format, using 2 decimal places. For example: The number 1200.2300001 would be became: 1200.23arrow_forwardQ1: 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.arrow_forwardWe want to print the character “*” as the following pattern. For example, for n = 5, we have a 5*5 .arrow_forward
