Here we consider a rook chess piece that is only allowed to move up by one square or to the right by one square. Now if we start it at the bottom left square of an 8 by 8 chessboard, then in order to take the rook from the bottom to the left to the top right square, we have to proceed the rook 7 steps forward and 7 steps rightward ( here the position of the rook is at the 1st left most and 1st down cornered most position which in the concept of cartesian we can say as (1,1) , not (0,0), thats why to reach at the position (8,8) , the rook has to move 7 forward steps and 7 rightward steps).
So the total number different ways to reach such position be 7x7=49.
Hence the answer.............
Thank you.............

In chess, the knight can move in eight directions. It can move two squares vertically followed by one square horizontally. It can also move two squares horizontally followed by one square vertically. Since the vertical motion can be up or down and the horizontal motion can be left or right, there are eight squares on a chessboard where a knight can be positioned after one move. Suppose that we have an n×n chessboard with a knight placed in one of...

King in N moves. In chess, a king can move one space in any of the 8 directions (2 vertical, 2 horizontal, 4 diagonals). Suppose our chessboard is infinite in every direction, and a king starts on a particular square. (a) How many different squares are possible locations for the king after N or fewer moves? (b) Answer the same question for a “crippled king” that can only move horizontally and vertically (no diagonal moves allowed). For both parts, show...

Please write code in java You’re given a chess board with dimension n x n. There’s a king at the bottom right square of the board marked with s. The king needs to reach the top left square marked with e. The rest of the squares are labeled either with an integer p (marking a point) or with x marking an obstacle. Note that the king can move up, left and up-left (diagonal) only. Find the maximum points the king...

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....

Rooks can move any number of squares horizontally or vertically on a chess board. The n rooks problem is to arrange rooks on an n×n board in such a way that none of the rooks could bump into another by making any of its possible horizontal or vertical moves. For this problem, the variables are each column (labeled 0, 1, ... , n−1), the the domain consists of each possible row (also labeled 0, 1, ... ,n−1). In each column...
