Python Please. An interesting puzzler for chess buffs is the Knight’s Tour problem, originally proposed by the mathematician Euler. Can the knight piece move around an empty chessboard and touch each of the 64 squares once and only once? We study this intriguing problem in depth here. The knight makes only L-shaped moves (two spaces in one direction and one space in a perpendicular direction). Thus, as shown in the figure below, from a square near the middle of an empty chessboard, the knight (labeled K) can make eight different moves (numbered 0 through 7). A: Draw an eight-by-eight chessboard on a sheet of paper, and attempt a Knight’s Tour by hand. Put a 1 in the starting square, a 2 in the second square, a 3 in the third, and so on. Before starting the tour, estimate how far you think you’ll get, remembering that a full tour consists of 64 moves. How far did you get? Was this close to your estimate? B: Now let’s develop a script that will move the knight around a chessboard…
Idiot’s Delight is a fairly simple game of solitaire, yet it is difficult to win. The goal is to draw all of the cards from the deck, and end up with no cards left in your hand. You will run through the deck of cards one time. Start by dealing 4 cards to your hand. You will always look at the last 4 cards in your hand. If the ranks of the “outer” pair (1st and 4th) are the same, discard all four cards. Otherwise, if the suits of the “inner” pair (2nd and 3rd) are the same, discard those 2 cards only. If you have less than 4 cards, draw enough to have 4 cards in your hand. If the deck is empty, the game is over. Your score will be the number of cards that remain in your hand. Like in golf, the lower the score the better.
Create a new Python module in a file named “idiots_delight.py”. Add a function called deal_hand that creates a standard deck of cards, deals out a single hand of 4 cards and returns both the hand and the deck. Remember that for the last assignment, you created several…
In mathematics, a prime number is a natural number greater than 1 that is not a product of two
smaller natural numbers, i.e. is it has only two factors 1 and itself. A natural number greater than
1 that is not prime is called a composite number. For example, 5 is prime because the only ways
of writing it as a product, 1 × 5 or 5 x 1, involve 5 itself.
Note that the prime number series is: 2, 3, 4, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, ..
a. Write a Java method named isPrime that takes a natural number as a parameter and returns the
if the given number is prime or not using the following header:
Public static boolean isPrime (int num)
b. Write a Java class called PrimeNumbers that:
Reads from the user a natural value n (should be less than or equal 200).
Prints a list of the prime numbers from 2 to n and their number and values.
The program has to work EXACTLY as given in the following sample run.
Hints:
You should create a single dimension array to store the prime…

- Correct answer will be upvoted else Multiple Downvoted. Computer science. pick a non-void adjacent substring of s that contains an equivalent number of 0's and 1's; flip all characters in the substring, that is, supplant all 0's with 1's, as well as the other way around; turn around the substring. For instance, think about s = 00111011, and the accompanying activity: Pick the initial six characters as the substring to follow up on: 00111011. Note that the number of 0's and 1's are equivalent, so this is a lawful decision. Picking substrings 0, 110, or the whole string would not be imaginable. Flip all characters in the substring: 11000111. Invert the substring: 10001111. Find the lexicographically littlest string that can be gotten from s after nothing or more tasks.

The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of bytes and returns a byte array containing a minimal sequence of moves that will lead to the solved board. The 2D array of bytes is “triangular” and represents a valid board configuration. Namely, the 2D array has 5 rows (0 – 4) and the size of every row is 1 more than its index. (e.g. Row 0 has length 1). The array contains one 0, five 1s, four 2s and five 3s. The solve method then returns an array of bytes representing a minimal sequence of moves that solves the puzzle. In other words, if the numbers from the returned array are used in order as inputs to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions that use fewer moves (although there could be other solutions that…arrow_forwardIn this project, a matrix of integers is given where each cell represents a weight. You are asked to write a program thatfinds a continuous path that combines any element of the first row with any element of the last row in the matrix. Thus,the sum of items along the way is minimized. When the matrix is drawn in the usual way, the path goes absolutely down.As shown in the table below, it's legal to switch from each cell directly to one of the three cells below it.

Obtain numerical positive integer values for m and n as inputs from the user. Generate random numbers and scale them down to either a “0” or a “1” according to whether they represent “Clean” or “Dirty”, respectively. After filling the array with 0s or 1s, start at some random array position indicating the initial position of the vacuum cleaner. First check if at that current position, there is the presence of a “Dirt” or not determined by whether 0 or 1 is filled in at that initial position of the vacuum cleaner. If there is a “Dirt”, clean it, and if there is no “Dirt” do a No-operation. After this is done, generate random numbers modulo 4 to obtain random numbers 0, 1, 2, 3 indicating whether to take a left, right, up or down correspondingly. If…arrow_forward
- The word ladder game was invented by Lewis Carroll in 1877. The idea is to begin with a start word and then change one letter at a time until you arrive at an end word. Each word along the way must be an English word. For example, starting from FISH, you can arrive at MAST through the following word ladder:FISH, WISH, WASH, MASH, MAST Write a program that uses recursion to find the word ladder given a start word and an end word, or that determines no word ladder exists. Use the file words.txt that is available online with the source code for the book as your dictionary of valid words. This file contains 87,314 words. Your program does not need to find the shortest word ladder between words; any word ladder will do if one exists. list aalii aardvark aardvarks aardwolf aba abaca abaci abacist aback abacus abacuses abaft abalone abalones abamp abampere abandon abandoned abandonee abandoner abandonersarrow_forwardI want to visualize/draw a traffic network in order to program a code that simulates it. The traffic network consists of N × N blocks and the road map forms a square lattice with (N + 1) × (N + 1) vertices or traffic junctions. On each street connecting two vertices, there are U units which randomly generate vehicles during the real-time simulation. When a vehicleis generated, it randomly chooses a unit in the system as its destination, and find a shortest path to move towards the destination.arrow_forwardWrite a function find_equivalent_matchings that takes a matching and returns all matchings with the same pattern (including the original one). Using this function, draw all matchings equivalent to {(0, 7), (1, 4), (2, 3), (5, 6)}. You might find it helpful to generate all permutations of a list using itertools.permutation (imported above) as in the following code template. perms=permutations (list_of_items) for p in perms:arrow_forward
