有这样一个故事:在太平洋中有A、B两个相邻的小岛.A岛居民都是诚实的人,B岛的居民都是骗子.当你问一个问题时,A岛的居民会告诉你正确的答案,而B岛的居民给你的答案都是错误的.一天,一个旅游者独自登上了两岛中的某个岛.他分辨不清这个岛是A岛还是B岛,只知道这个岛上的人既有本岛的居民又有另一岛的来客.他想问岛上的人“这是A岛还是B岛?”
There is such a story: There are two adjacent islands in the Pacific Ocean, A and B. The residents of A-island are all honest people, and the residents of B-island are all liar. When you ask a question, the residents of A-island will tell Your correct answer, and the answer given to you by the residents of island B is wrong. One day, a tourist alone climbed onto an island in the two islands. He could not tell whether the island was island A or island B. I know that the people on this island have both residents of the island and guests from another island. He wants to ask people on the island “This is A Island or B Island?”
