There are 32 students standing in a classroom. Two different algorithms are given for finding the average height of the students.Algorithm AStep 1: All students stand.Step 2: A randomly selected student writes his or her height on a card and is seated.Step 3: A randomly selected standing student adds his or her height to the value on the card, records the new value on the card, and is seated. The previous value on the card is erased.Step 4: Repeat step 3 until no students remain standing.Step 5: The sum on the card is divided by 32. The result is given to the teacher.Algorithm BStep 1: All students stand.Step 2: Each student is given a card. Each student writes his or her height on the card.Step 3: Standing students form random pairs at the same time. Each pair adds the numbers written on their cards and writes the result on one student's card; the other student is seated. Theprevious value on the card is erased.Step 4: Repeat step 3 until one student remains standing.Step 5: The sum on the last student's card is divided by 32. The result is given to the teacher.Which of the following statements is true?

Create an algorithm that prints all possible arrangements for eight queens on an 8x8 chess board so that no two queens share the same row, column, or diagonal. In this example, "diagonal" refers to all diagonals, not simply the two that cut the board in half.
Union-Find: Maze Write a program that generates mazes of arbitrary size using the union-find algorithm. A simple algorithm to generate the maze is to start by creating an N x M grid of cells separated by walls on all sides, except for entrance and exit. Then continually choose a wall randomly, and knock it down if the cells are not already connected to each other. If we repeat the process until the starting and ending cells are connected, we have a maze. It is better to continue knocking down the walls until every cell is reachable from every cell as this would generate more false leads in the maze. Test you algorithm by creating a 15 x 15 grid, and print all the walls that have been knocked down. D
Celebrity problem A celebrity among a group of n people is a person who knows nobody but is known by everybody else. The task is to identify a celebrity by only asking questions to people of the form: ”Do you know him/her?” Solution Select two people from the group given, say, A and B, and ask A whether A knows B. If A knows B, remove A from the remaining people who can be a celebrity; if A doesn’t know B, remove B from this group. Solve the problem recursively for the remaining group of people who can be a celebrity Which design strategy does the following solution use?

Artificial Intelligence - Local Search Starting from a randomly generated state of the 15-puzzle game (https://en.wikipedia.org/wiki/15_puzzle), steepest-ascent hill-climbing (the vanilla version of hill-climbing search) gets stuck 76% of the time, i.e., solving only 24% of problem instances. But it works very quickly, i.e., it takes just 6 steps on average when it succeeds and 5 steps when it gets stuck. In contrast, if sideways moves are allowed, this raises the percentage of problem instances solved by hill-climbing from 24% to 81%, with the success at a cost: the algorithm averages roughly 7 steps for each successful instance and 32 steps for each failure. Now suppose that we are implementing random-restart hill climbing (i.e., if a search fails, it keeps to try, and try, until it gets a success) by the following two versions: one uses vanilla steepest-ascent hill climbing, and the other one uses hill climbing with sideways moves. Can you please tell which version of…

Children often play a memory game in which a deck of cards containing matching pairs is used.The cards are shuffled and placed face down on a table. The players then take turns and selecttwo cards at a time. If both cards match, they are left face up; otherwise, the cards are placed facedown at the same positions. Once the players see the selected pair of cards and if the cards do notmatch, then they can memorize the cards and use their memory to select the next pair of cards.The game continues until all the cards are face up. Write a program to play the memory game.Use a two-dimensional array of 4 rows and 4 columns for a deck of 16 cards with 8 matchingpairs. You can use numbers 1 to 8 to mark the cards. Use random number generators to randomlystore the pairs in the array. Use appropriate functions (see below) in your program, and themain program should be merely a call to functions.Your program should consist of at least the following functions:a.

Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. Ridbit begins with an integer n. In one action, he can perform one of the accompanying tasks: partition n by one of its appropriate divisors, or take away 1 from n in case n is more prominent than 1. An appropriate divisor is a divisor of a number, barring itself. For instance, 1, 2, 4, 5, and 10 are appropriate divisors of 20, however 20 itself isn't. What is the base number of moves Ridbit is needed to make to decrease n to 1? Input The principal line contains a solitary integer t (1≤t≤1000) — the number of experiments. The main line of each experiment contains a solitary integer n (1≤n≤109). Output For each experiment, output the base number of moves needed to lessen n to 1.

Substitution ciphers are encryption/decryption algorithms that replace one letter or number with another. The first attested use of a substitution cipher in military affairs was by Julius Caesar, described by him in Gallic Wars (cf. Kahn pp83-84). In caesar cipher , you replace each letter by 3rd letter on. If it is out of bound (later than Z), then round to the head (letter A) and continue the shift. For example:meet me after the toga party PHHW PH DIWHU WKH WRJD SDUWB Please write a program in Java to implement the Caesar Cipher: a. Implement the encryption algorithm. Ask the user to input one all lower case normal sentence (called plaintext) using the nextLine method, and then output the encrypted text (called ciphertext). b. Implement the decryption algorithm. Ask the user to input one encrypted sentence (i.e. ciphertext) using the nextLine method, and then output the decrypted text (i.e. plaintext).
