The Drunkard’s Walk. A drunkard in a grid of streets randomly picks one of four directions and stumbles to the next intersection, then again randomly picks one of four directions, and so on. You might think that on average the drunkard doesn’t move very far because the choices cancel each other out, but that is not the case.
Represent locations as integer pairs (x, y). Implement the drunkard’s walk over 100 intersections, starling at (0,0), and print the ending location.

- One variation on the game of nim is described in Luger. The game begins with a single pile of stones. The move by a player consists of dividing a pile into two piles that contain an unequal number of stones. For example, if one pile contains six stones, it could be subdivided into piles of five and one, or four and two, but not three and three. The first player who cannot make a move loses the game. (5.1) Draw the complete game tree for this version of Nim if the start state consists of six stones. (5.2) Perform a minimax evaluation for this game. Let 1 denote a win and 0 a loss.arrow_forwardJava - Musical Note Frequenciesarrow_forwardPLEASE CODE IN PYTHON The Penny Pitch game is popular in amusement parks. Pennies are tossed onto a board that has certain areas marked with different prizes. For example: The prizes available on this board are puzzle, game, ball, poster, and doll. At the end of the game, if all of the squares that say BALL are covered by a penny, the player gets the ball. This is also true for the other prizes. The board is made up of 25 squares (5 x 5). Each prize appears on three randomly chosen squares so that 15 squares contain prizes.In Python, create a PennyPitch application that displays a Penny Pitch board (use [ and ] to indicate squares) with prizes randomly placed and then simulates ten pennies being randomly pitched onto the board. After the pennies have been pitched, the application should display a message indicating which prizes have been won, if any.arrow_forward
- 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…arrow_forwardA popular word game involves finding words from a grid of randomly generatedletters. Words must be at least three letters long and formed from adjoining letters.Letters may not be reused and it is valid to move across diagonals. As an example,consider the following 4 * 4 grid of letters: A B C DE F G HI J K LM N O P The word “FAB” is valid (letters in the upper left corner) and the word “KNIFE”is valid. The word “BABE” is not valid because the “B” may not be reused. Theword “MINE” is not valid because the “E” is not adjacent to the “N”. Write a program that uses a 4 * 4 two-dimensional array to represent the gameboard. The program should randomly select letters for the board. You may wishto select vowels with a higher probability than consonants. You may also wish toalways place a “U” next to a “Q” or to treat “QU” as a single letter.

You have a 2n by 2n squareboard of squares. You have a sufficient number of tiles each with the shape . Your goalis to place nonoverlapping tiles on the board to cover each of the 2n × 2n tiles except forthe single square at location i, j. Give a recursive algorithm for this problem in whichyou place one tile yourself and then have four friends help you. What is your base case?arrow_forward

For each configuration, the only possible moves are to swap the empty tile with one of its neighboring tiles. The goal state for the puzzle consists of tiles 1-3 in the top row, tiles 4-6 in the middle row, and tiles 7 and 8 in the bottom row, with the empty space in the lower-right corner. In this section, you will develop two solvers for a generalized version of the Eight Puzzle, in which the board can have any number of rows and columns. We have suggested an approach similar to the one used to create a Lights Out solver in Homework 2, and indeed, you may find that this pattern can be abstracted to cover a wide range of puzzles. If you wish to use the provided GUI for testing, described in more detail at the end of the section, then your implementation must adhere to the recommended interface. However,…arrow_forward
- Start with a pile of n stones and successively split a pile into two smaller piles until each pile has only one Each time a split happens, multiply the number of stones in each of the two smaller piles. (For example, if a pile has 15 stones and you split it into a pile of 7 and another pile of 8 stones, multiply 7 and 8.) The goal of this problem is to show that no matter how the pile of n stones are split, the sum of the products computed at each split is equal to n(n - 1)/2. Using strong mathematical induction, prove that no matter how the pile of n stones are split, the sum of the products computed at each split is equal to n(n - 1)/2.arrow_forwardCan u solve this ?arrow_forwardLittle Frank loves mathematics. Every day, he solves some mathematical problems to improve his skill. A few days ago, he found a popular problem about turtles. The problem is as follows. Little Frank is given R rectangles, numbered 1 through R. The width and height of the i-th rectangle are Ni and M¡ unit respectively. There is a turtle located on the top-left corner of each rectangle. For each rectangle, count the number of ways the turtle can reach the bottom-right corner, if each turtle can only move right or down 1 unit at any time. The turtle is not allowed to move outside the rectangle, but, of course, the turtle can move on the boundary of the rectangle. In less than one second, this problem was solved for all rectangles. He felt that the problem was too easy. This morning, Little Frank wanted more challenges. Thus, for each rectangle į, he cut and removed a rectangle of A¡ x Bị unit from the top-right corner. See the following figure for detail. Bị Mi He could not solve this…arrow_forward
