用C++语言实现棋盘覆盖分治算法 在一个2k×2k 个方格组成的棋盘中，恰有一个方格与其它方格不同，称该方格为一特殊方格，且称该棋盘为一特殊棋盘。在棋盘覆盖问题中，要用4种不同形态的L型骨牌覆盖给定的特殊棋盘上除特殊方格以外的所有方格-C++ language with the board divided coverage of a 2k × 2k Algorithm in the composition of the board of squares, just a different box with the other box, saying that the box is a special box, and said the board is a special board. Cover problem in the board, the use of 4 different forms of L-type domino given special coverage on the board except in special box outside of all boxes
