Chapter 7, Problem 7.24E
(Eight Queens) Another puzzler for chess buffs is the Eight Queens problem. Simply stated: Is it possible to place eight queens on an empty chessboard so that no queen is "attacking" any other. i.e., no two queens are in the same row, the same column. or along the same diagonal? Use the thinking the developed in Exercise 7.22 to formulate a heuristic for solving the Eight Queens problem. Run
7.26 The 22 squares eliminated by placing a queen in the upper-left corner.

[Fish
Tank]
You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j.
When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that
is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving
right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly
m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size.
The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…
(Data Structures and Algo C++ Weiss 4th ed - ch7.40):
The following divide-and-conquer algorithm is proposed for finding the simultaneous maximum and minimum: If there is one item, it is the maximum and minimum, and if there are two items, then compare them, and in one comparison you can find the maximum and minimum. Otherwise, split the input into two halves, divided as evenly as possibly (if N is odd, one of the two halves will have one more element than the other). Recursively find the maximum and minimum of each half, and then in two additional comparisons produce the maximum and minimum for the entire problem.
In C++, find a function which will take in a vector and solve the problem, producing a vector of two elements, the min and max.
(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…

- (GREATEST COMMON DIVISOR) The greatest common divisor of integers x and y is the largest integer that evenly divides into both x and y. Write and test a recursive function gcd that returns the greatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equal to 0, then gcd (x, y) is x; otherwise, gcd (x, y) is gcd (y, x % y), where % is the remainder operator.arrow_forward(Computer-Assisted Instruction: Reducing Student Fatigue) One problem in CAI environments is student fatigue.

Possible responses to an incorrect answer: No. Please try again.Wrong.

Do not use anything more advanced than a loop, such as functions or arrays or classes. In the card game named 'blackjack' players get two cards to start with, and then they are asked whether or not they want more cards. Players can continue to take as many cards as they like. Their goal is to get as close as possible to a total of 21 without going over. Face cards have a value of 10. Write a command line game that plays a simple version of blackjack. The program should generate a random number between 1 and 10 each time the player gets a card. Each of the values (1 through 10) must be equally likely. (In other words, this won't be like real black jack where getting a 10 is more likely than getting some other value, because in real black jack all face cards count as 10.) It should keep a running total of the players cards, and ask the player whether or not it should deal another card. Sample output for the game is written…arrow_forward(Recursive Greatest Common Divisor) The greatest common divisor of integers x and y isthe largest integer that evenly divides both x and y.

- DO NOT USE EXISTING ANSWERS ON CHEGG OR COURSE HERO OR ANY OTHER SERVICES PLEASE! Thanks :) CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit. Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated.

- 4arrow_forward[Python Language] Using loops of any kind, lists, or is not allowed. Angela loves reading books. She recently started reading an AI generated series called “Harry Trotter”. Angela is collecting books from the series at her nearest bookstore. Since the series is AI generated, the publishers have produced an infinite collection of the books where each book is identified by a unique integer. The bookstore has exactly one copy of each book. Angela wants to buy the books in the range [l,r], where l ≤ r. As an example, the range [−3,3] means that Angela wants to buy the books − 3, − 2, − 1, 0, 1, 2, and 3. Dan also loves the series (or maybe annoying Angela – who knows, really), and he manages to sneak into the bookstore very early to buy all of the books in the range [d,u], where d ≤ u. When Angela later visits, sadly she will not find those books there anymore. For example, if Angela tries to buy books [−2,3] and Dan has bought books [0,2], Angela would only receive books − 2, − 1,…arrow_forward(JAVA) A smart home has a number of equipment attached to it. Examples TV, Refrigerator, Alexa, VideoGame, Lamp.... Each one of them with its specific functions, all of which have a shared on/off function (in addition to others).

Implement the proof of concept for this manager. Implement at least 6 different pieces of equipment. Give specific behaviors for each.arrow_forward
