中国是数学的故乡.类似“五猴分桃”的“分鱼问题”,在我国民间早就广泛流传.原题是:“三个人在湖里打鱼,共打鱼若干条,然后在湖边休息睡觉.甲醒来后,把鱼分成三堆,每堆一样多,剩下一条,他拿走了其中的一堆,把剩下的一条扔在另外两堆内.乙醒来后,也照样把鱼分成三堆,剩下两条,他拿走了一堆,把所剩下两条扔在另外两堆内.丙醒后,照样把鱼分 China is the hometown of mathematics. Similar to the problem of “fetching fish with five monkeys”, it has long been widely circulated in our country’s civil society. The original title was: “Three people are fishing in the lake and fish are used in several ways. Then they are in the lake. Resting and sleeping. After waking up, the fish was divided into three piles. Each pile was as large as the rest. He took one of them and threw the rest in two other piles. After waking up, He also divided the fish into three piles, leaving the other two. He took a pile and threw the remaining two into the other two piles. After he wakes up, he still divides the fish.
