◆L SHAPE
If the two legs of an "L" shape are not the same length, let's call it a
nonregular "L". How many different nonregular L's can be formed using the
squares of an 8x8 chessboard? If the problem was asked for a 3x3 board,
the answer would be 16.
"L"形的两只脚长短不一样时,我们称作非正规"L"形。
问8x8的棋盘上可以形成多少种不同的非正规"L"形?
若是问3x3的棋盘,则答案为16。
