1998年平江初中数学竞赛中有这样一道题：“48根火柴分成三堆，从第一堆中取出与第二堆一样多的火柴放入第二堆；再从第二堆中取出与第三堆一样多的火柴放入第三堆；又从第三堆火柴中取出与此时的第一堆一样多的火柴放入第一堆，这样，三堆火柴就变成一样多问原来三堆各有多少? In the 1998 Pingjiang Junior High School Mathematics Contest, there was such a question: "48 matches are divided into three piles. Take out as many matches as the second pile from the first pile into the second pile; and remove from the second pile and third. As many stacks of matches are put into the third pile; from the third pile of matches, the same number of matches as the first pile at this time are put into the first pile, so that the three piles of matches become as much as the original three piles. How many are each?
