This project implements the solution to the following problem: NOVEMBER CHALLENGE: Our first challenge will be relatively simple, but a small twist: you have to write it in a language you have never written in before. I don’t care what it is, how popular or obscure it is, as long as you have never written anything in it. Your task is to write a program that reads a chessboard configuration and identifies whether a king is under attack (in check). A king is in check if it is on square which can be taken by the opponent on his next move. White pieces will be represented by uppercase letters, and black pieces by lowercase letters. The white side will always be on the bottom of the board, with the black side always on the top. For those unfamiliar with chess, here are the movements of each piece: Pawn (p or P): can only move straight ahead, one square at a time. However, it takes pieces diagonally, and that is what concerns you in this problem. Knight (n or N) : has an L-shaped movement shown below. It is the only piece that can jump over other pieces. Bishop (b or B) : can move any number of squares diagonally, either forward or backward. Rook (r or R) : can move any number of squares vertically or horizontally, either forward or backward. Queen (q or Q) : can move any number of squares in any direction (diagonally, horizontally, or vertically) either forward or backward. King (k or K) : can move one square at a time in any direction (diagonally, horizontally, or vertically) either forward or backward. Movement examples are shown below, where “*” indicates the positions where the piece can capture another piece: Pawn Rook Bishop Queen King Knight ........ ...*.... .......* ...*...* ........ ........ ........ ...*.... *.....*. *..*..*. ........ ........ ........ ...*.... .*...*.. .*.*.*.. ........ ..*.*... ........ ...*.... ..*.*... ..***... ..***... .*...*.. ...p.... ***r**** ...b.... ***q**** ..*k*... ...n.... ..*.*... ...*.... ..*.*... ..***... ..***... .*...*.. ........ ...*.... .*...*.. .*.*.*.. ........ ..*.*... ........ ...*.... *.....*. *..*..*. ........ ........ Remember that the knight is the only piece that can jump over other pieces. The pawn movement will depend on its side. If it is a black pawn, it can only move one square diagonally down the board. If it is a white pawn, it can only move one square diagonally up the board. The example above is a black pawn, described by a lowercase “p”. We use “move” to indicate the squares where the pawn can capture another piece. Getting Started Input There will be an arbitrary number of board configurations in the input, each consisting of eight lines of eight characters each. A “.” denotes an empty square, while upper and lowercase letters represent the pieces as defined above. There will be no invalid characters and no configurations where both kings are in check. You must read until you find an empty board consisting only of “.” characters, which should not be processed. All boards, except for the empty one, will contain exactly one white king and one black king. Output For each board configuration read you must output one of the following answers: Game #d: white king is in check. Game #d: black king is in check. Game #d: no king is in check. where d stands for the game number starting from 1. Sample Input Text File ..k..... ppp.pppp ........ .R...B.. ........ ........ PPPPPPPP K....... rnbqk.nr ppp..ppp ....p... ...p.... .bPP.... .....N.. PP..PPPP RNBQKB.R ........ ........ ........ ........ ........ ........ ........ ........ Sample Output Game #1: black king is in check. Game #2: white king is in check. If you get this far quickly and want to take it further: BONUS ROUND: Determine not only if a king is in check, but also checkmate. EXTRA BONUS ROUND: If king is in check, determine best solution to get out of check. Please list in your comments how you determined “best” solution to get out of check.
