If a game ends with a winner, your program should print white win! or black win!. Here is an example run of the program (The bold text represents the SN input by user, the output is the corresponding LN): In this question, you will write a program to convert SN into long notation (LN). To specify a piece, we use w and b to represent White and Black then p for Pawn, n for kNight, b for Bishop, r for Rook, q for Queen and k for King. Ensure you understand the basics of chess before proceeding. We will use a short notation (SN) for chess games, as shown in the example below. You can only capture an opponent piece but not your own. A pawn cannot move diagonally without capturing a piece. As a reminder: - A move is considered invalid if the king is in check after the move. You should check the Wikipedia article for the valid moves for each piece. Each move involves two positions (from and to) and checkmate is the only way to end a game, The game consists only of alternating moves (and captures) between White and Black until checkmate. In this question, we will consider a simplified version of chess with no castling, en passant, promotion, resignation, time control, draw, stalemate, etc.

Read this Wikipedia article to learn about chess. Chess is a two player board game, with each player controlling an army of chess pieces (White and Black) aiming to checkmate the opponent's king.
