The chef gives you an A sequence of N's length. Let X mean MEX for A sequence. The cook is interested in calculating the correct values k, so that, if the whole part of Ai A is replaced by max (Ai – k, 0), the MEX sequence remains X.. Find calculations for such values. If there are such endless numbers, print - 1 instead. As a friendly reminder, MEX sequence is the smallest non-negative number non-sequential.

- : 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.HangmanAA.java For this program, you will create the game Hangman. (If you are unsure of how to play Hangman, Google it.) The game will start by asking player 1 for a word or phrase (can be multiple words). Then player 1 will be asked how many missed guesses are allowed by player 2. Once this information is received, player 2 will take over. (Have the program print many blank lines of space so that player 2 can’t see what player 1 entered.) The instructions should be displayed for player 2 as well as the number of misses they’re allowed to make before they lose the game. The screen should also output dashes or underscores to represent each letter of player 1’s secret word/phrase. Player 2 should guess one letter at a time. Case should not matter. Typing x or X should give the same result. If that letter is present in the mystery phrase, then it should be displayed. (It will replace the dash/underscore in that spot. Spaces, punctuation, and all other non-alphabetic characters should…this code should be in python: you will be implementing a simple Tic-Tac-Toe game without the graphics.Here is how it works: • First, it is randomly determined if the user starts the game or the computer and thisinformation is shown to the user. The player who starts always starts as “X”.• The players (computer and the user) will then take turns in playing. The computer willchoose a random empty spot on its turn. The user enters its choice in the console.• Each of the empty spots have a corresponding number that the players choose on theirturn. If the user enters anything other than the number of an empty spot (not yet filledwith “X” or “O”), it will not be accepted, and they will be prompted to enter a correctnumber. • After each turn, two things need to be done: 1) displaying the updated board 2) checkingif anyone has…
- Help code in Java 21. Compound InterestWhen a bank account pays compound interest, it pays interest not only on the principal amount thatwas deposited into the account, but also on the interest that has accumulated over time. Suppose youwant to deposit some money into a savings account, and let the account earn compound interest for acertain number of years. The formula for calculating the balance of the account after a specifiednumber of years is:A = P ( 1 + r n ) n tThe terms in the formula are:A is the amount of money in the account after the specified number of years.P is the principal amount that was originally deposited into the account.r is the annual interest rate.n is the number of times per year that the interest is compounded.t is the specified number of years.Write a program that makes the calculation for you. The program should ask the user to input thefollowing:The amount of principal originally deposited into the accountThe annual interest rate paid by the accountThe…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.In Java (Use the isPrime Method) PrimeNumberMethod.java, provides the isPrime(int number) method for testing whether the number is prime. Use this method to find the number of prime numbers less than 10000. Below are some clarifications for the Java program (a) The lab is to COUNT the prime numbers less than 10000. Do NOT list the prime numbers. (b) A pair prime is two prime numbers whose difference is 2. For e.g. 3,5; 11,13; 17, 19; etc. We can use IsPrime function to count how many pair primes are there in a range from 2 to 100 for example. Create a function pairPrime, that takes one argument. pairPrime should return the number of pair primes between 2 and the argument passed. Use the pairPrime function to count the pair primes between 2 and 1000. Make use of the IsPrime function to solve this task. (This feature is worth 8 points). Use the compile/run button to test tour program. Include the output displayed. It will be similar to: command>javac…
- please code in python You place a pawn at the top left corner of an n-by-n chess board, labeled (0,0). For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below. For example: Enter a board size: 4 1 0 0 0 1 1 0 0 1 2 1 0 1 3 3 1Problem 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.…P1 P2 P3 P4 A pentagonal number is one that corresponds to dots arranged into a pentagon. Above are the first four pentagonal numbers and their pentagons. The pentagonal number PN has sides made of N dots. When you count the dots for a pentagonal number, include the dots for the inner pentagons. So to figure out how many dots PN has, find out how many P(N-1) has and add the dots for the new sides of size N. P1 = 1, P2 = 5, P3 = 12, P4 = 22 Figure out a recursive formula for PN and then write a function that implements it. That is, implement pentagonal() using recursion. pentagonal(1) -> 1 pentagonal(2) -> 5 pentagonal(3) -> 12
- Java Programming: Write a program that reads five integer values from the user, then analyzes them as if they were a hand of cards. When your program runs it might look like this (user input is in orange for clarity): Enter five numeric cards, no face cards. Use 2 - 9. Card 1: 8 Card 2: 7 Card 3: 8 Card 4: 2 Card 5: 9 Pair! (This is a pair, since there are two eights). You are only required to find the hands Pair and Straight.Java Only Solution: John's barn has a fence consisting of N consecutive sections numbered from left to right from 1 to N. Each part is first painted in one of two colors: red or green, your information is given with string C. The color of the I-th part Ci will be equal to 'R' if the color of the part is red and 'G' if it is green. John decided to paint the whole fence green. To make the normal drawing process more fun he decided to do it using the following process. Every minute (until the whole fence is painted green) you will do the following steps: Select any part of the phone that is painted red. Let's show the index of this section as X. In each section with references X, X + 1, ..., min (N, X + K - 1), flip the color of the corresponding part from red to green and from green to red by re-painting. John wonders how quickly he can paint the phone. Please help her find the minimum number of minutes needed to repaint. Input: 1 73 RGGRGRG Output: 4use 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.
