◆CHESS CODES
Sixty four chess notation codes from a1 to h8 are placed randomly on each
square of a standard 8x8 chessboard. Your task is to put the codes in the
correct order as given in the diagram. In each step you can take one code
from a white square and one code from a black square and exchange them.
What is the minimum number of steps that is sufficient to obtain the correct
order from all possible initial positions?
六十四個西洋棋代數記號由 a1 至 h8 隨機放置在一個標準 8x8 的西洋棋盤上。
你的任務是將所有記號回歸到正確的位置上。
每一步你能做的是將一個處在黑格的記號和一個處在白格的記號對調。
試問對所有盤面,多少步足以將所有記號回歸?
