Question
Chapter 7, Problem 17.3E
Program Plan Intro
- int[] horizontal, vertical: arrays containing the horizontal and vertical displacement values for each of the knight's moves respectively.
- int[][] board: a 2-dimensional array representing the chessboard.
- int currentRow, currentColumn, moveNumber, minAccessibility, accessibility: int variables representing the current row position of the knight, current column position of the knight, current move number of the knight, minimum accessibility of all possible moves for the knight, and the number of possible moves from a given position, respectively.
The methods used in the program are as follows:
- run(): a public void method that initializes the knight's starting position and iterates through all possible moves until the end of the tour or no more valid moves are available
- getNextMove(int currentRow, int currentColumn): a private static method that determines the next best move for the knight based on accessibility and validity of the move
- isValidMove(int row, int column): a private static method that checks whether a given move is valid based on the chessboard's boundaries
- getAccessibility(int row, int column): a private static method that calculates the number of possible moves from a given position on the chessboard.

Artificial Intelligence (Part - 1)
====================
The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk.

- Function is given:-arrow_forwardPart 2: Binary Arithmetic One of the most common operations we perform on binary numbers (and all numbers) is addition. It can be cumbersome to convert your binary numbers to decimal just to add them and convert them back, so instead we will be learning how to add binary numbers directly. Binary addition works the same way as decimal addition, with the added restriction that each digit can only go up to 1. Let's consider the possibilities for adding the values of any 2 single digits together: 0 + 0 0 + 1 1 + 0 1 + 1 0 1 1 10 (remember that 10 in binary represents the number 2) In that last case, the result is larger than a single digit. When adding larger binary numbers, that means we have to carry the 1 over to the next column. This presents us with another new case: what happens if we have 1 + 1 + carried 1? In that case, the result is 11, which means that column's result is 1, and we carry 1 to the next column.

- The king and the Chees board. A king is so impressed by one of his courtiers thet he offers to give him whatever he desires. The wily courtier replies that all he wants are some grains, as many as could be placed on each square of a chess board. Specially, grains are to be placed on each square of a chess board, as follows. One grain is to be placed in the first square,two in the second square , four in the third square and so on. (We'll assume the squares are big enough to accommodate the increasing numbers of grains they're each expected to hold). Assuming anNxN chess board, WAP in java that displays the exacy number of grains required to cover an NxN board.

For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ftarrow_forwardFor every of 4 statements prove its correctness.arrow_forward
- What role does the reflection vector play in computer graphics? The following should have at least two examples of each.arrow_forwardRecursion can be direct or indirect. It is direct when a function calls itself and it is indirect recursion when a function calls another function that then calls the first function. To illustrate solving a problem using recursion, consider the Fibonacci series: - 1,1,2,3,5,8,13,21,34...The way to solve this problem is to examine the series carefully. The first two numbers are 1. Each subsequent number is the sum of the previous two numbers. Thus, the seventh number is the sum of the sixth and fifth numbers. More generally, the nth number is the sum of n - 2 and n - 1, as long as n > 2.Recursive functions need a stop condition. Something must happen to cause the program to stop recursing, or it will never end. In the Fibonacci series, n < 3 is a stop condition. The algorithm to use is this: 1. Ask the user for a position in the series.2. Call the fib () function with that position, passing in the value the user entered.3. The fib () function examines the argument (n). If n < 3…arrow_forwardPlease show work as well as typed answer for part A and Barrow_forward
