3. Eight Queens Write a program that places eight queens on a chessboard (8 x 8 board) such that no queen is "attacking" another. Queens in chess can move vertically, horizontally, or diagonally. How you solve this problem is entirely up to you. You may choose to write a recursive program or an iterative (i.e., non-recursive) program. You will not be penalized/rewarded for choosing one method or another. Do what is easiest for you. 3.1. Output Below...

5. Consider the grid shown below; one can imagine that it is a map of roads in a city. In this problem we consider the problem of moving from one corner of the grid to another. A B C 1 (a) Suppose that, starting at the point labeled A, you can go one step up or one step to the right at each move, as long as you stay on the grid. If you end up at the point labeled...

5. Let F(n, m) denote the number of paths from top-left cell to bottom-right cell in a (n x m) grid (that only permits moving right or moving down). It satisfies the recurrence relation F(n, m) F(n-1, m) + F(n, m-1) What should be the initial condition for this recurrence relation? (Hint: What would be the number of paths if there was only a single row or a single column in the grid?)[5] Convince yourself that F(n, m) gives correct...

4. Consider a rook chess piece that is only allowed to move up by one square or to the right by one square. If we start it at the bottom left square of an 8 by 8 chessboard, how many different paths are there that the rook can take from the bottom left to the top right square?

Four point charges are placed at the corners of a square as shown in the figure. Each side of the square has length 2.0 m. Determine the magnitude of the electric field at the point P, the center of the square. Top right corner has a charge of 1 uC, bottom right corner has a charge of +4 uC, top left corner has a charge of +4 uC (top left and bottom right corners cancel out), and bottom left corner...

4. Eight rooks are placed randomly on a chess board. What is the probability that none of the rooks can capture any of the other rooks? (In non-chess terms: Randomly pick 8 unit squares from an 8 x 8 square grid. What is the probability that no two squares share a row or a column?) Hint: How many choices do you have to place rooks in the first row? After you have made your choice, how many choices do you...

A robot is standing at the origin (0,0) of a square grid. The robot is programmed to move exactly one unit at a time, in one of three directions: up, down, and right. The robot will never move left. For example, starting at (0,0), the robot will move either • one unit up, to (0,1), one unit down, to (0,-1), or • one unit right, to (1,0). . The robot is programmed to make exactly 5 moves, and then stop....

Write a JAVA program that plays a simple Pac-man game. The game plays on a 10 by 10 grid (absolutely, you can make it bigger). Pac-man is depicted as “#” and others as “*”. Please see the below. You should ask how many pac-man plays before starting the game. Then, you should create the number of pac-man objects. The pac-mans are defined as classes, and the objects are stored in an array. The pac-man class has a “move()” method, which...

This assignment requires you to write a program to implement an odd-order Magic Square. Prompt the user to enter the “order” of the square and then produce for the user a magic square of that order. Run your code for at least four different inputs – all odd. ODD ORDER MAGIC SQUARES 1. Start by placing 1 in the middle column of the top row. 2. Continue by always placing the next number (say k+1) in the square diagonally up...

4. Consider a chessboard, shown below. At starting at the square al (the lower right hand corner), you can go one step up or one step right at each move. The procedure stops until the point h8 (the upper right corner) is reached. a) How many different paths from al to h8 are possible? (b) How many differnt paths from al to h8 are possible if each path must pass through the square e4? 5. If 10 new teachers are...
