- Knight's Tour: The Knight's Tour is a mathematical problem involving a knight on a chessboard. The knight is placed on the empty board and, moving according to the rules of chess, must visit each square exactly once. There are several billion solutions to the problem, of which about 122,000,000 have the knight finishing on the same square on which it begins. When this occurs the tour is said to be closed. Your assignment is to write a program that gives a solution to the Knight's Tour problem recursively. You must hand in a solution in C++ AND Java. The name of the C++ file should be "main.cc" and the name of the Java file should be "Main.java". Write C++ only with a file name of main.cc Please run in IDE and check to ensure that there are no errors occuring Output should look similar to: 1 34 3 18 49 32 13 16 4 19 56 33 14 17 50 31 57 2 35 48 55 52 15 12 20 5 60 53 36 47 30 51 41 58 37 46 61 54 11 26 6 21 42 59 38 27 64 29 43 40 23 8 45 62 25 10 22 7 44 39 24 9 28 63Please correct the error for this code: import java.util.Scanner; // import Scanner class required to accept input from userpublic class Main // To declare 3 variables for employee ID, Name and Salary{ public static void main(String[] args) { int i; int num; Scanner obj = new Scanner(System.in); System.out.print("Enter number of employees: "); // user should enter the number of employees int num = obj.nextInt(); Employee emp[] = new Employee[num]; // create an array of num for (i = 0; i < num; i++) { Employee e = new Employee(ID, Name, Sal); emp[i] = e; System.out.println("Employee details: "); // To store the employees details System.out.print("Enter ID: "); int ID = obj.nextInt(); System.out.print("Enter Name: "); String Name = obj.nextLine(); System.out.print("Enter Salary: "); double Sal =…please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]

- ONLY IF STATEMENTS ALLOWED!!!! NO RANGE FUNCTION, NO SETS, NO LISTS, NO LOOPS, ETC 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…(Coding Language C++) Dynamic Programs Hoskins College offers both curriculum and continuing education courses.

- 23.8 LAB: Consecutive heads (Use Python) Given main() and GVCoin class, complete function consecutive_heads() that counts and returns the number of flips taken to achieve a desired number of consecutive heads without a tails. Function consecutive_heads() has a GVCoin object and an integer representing the desired number of consecutive heads without a tails as parameters. Note: For testing purposes, a GVCoin object is created in the main() function using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 15 during development, but when submitted, a different seed value will be used for each test case. Refer to the textbook section on random numbers to learn more about pseudo-random numbers. Ex: If the GVCoin object is created with a seed value of 15 and the desired number of consecutive heads is 5, then the function consecutive_heads() returns 16 and the program outputs: Total number of flips for 5 consecutive heads: 16Code in C++ Language As a cashier, you would always hate those times when customers choose to take back their order since you'd always summon your manager and yell, "Ma'am pa-void!" No matter how you hate it, you always have to do it since you have no other choice. Given (1) an array of prices of the items, (2) another array of the items the customer wishes to take back, and (3) the customer's payment, print the change of the customer. Input: The first number indicates the number of items "n" brought to the cashier. The next "n" numbers are the prices of the items. The next number indicates the number of items "m" that the customer wants to take back and not proceed. It is assured that 0 <= m <= n. The next "m" numbers are the items to be void that ranges from item 1 to item "n". The final number is the customer's payment. It is also assured that the given payment >= final price of items.
