Cantor 表问题： 问题描述： 把分子和分母均小于108 的分数按下面的办法排成一个数表。 1/1 1/2 1/3 1/4 1/5 ... 2/1 2/2 2/3 2/4 2/5 ... 3/1 3/2 3/3 3/4 3/5 ... 4/1 4/2 4/3 4/4 4/5 ... 5/1 5/2 5/3 5/4 5/5 ... ... ... 我们以Z 方形方法给上表的每项编号。第一项是1/1，第二项是1/2， 然后是2/1，3/1，2/2，1/3，1/4，2/3，3/2，4/1，5/1，4/2，...... 要求:对于给定的输入的编号N(0<N<10000)，能够输出其中的第N 项。 如： 输入N = 7； 输出1/4。-Cantor Table : Problem descr iption : put both the numerator and the denominator of the fraction is less than 108 by the following methods formed a few tables. 1 / 1 1 / 2 1 / 3 1 / 4, 1 / 5 ... 2 / 1 2 / 2 2 / 3 2 / 4 2 / 5 ... 3 / 1, 3 / 2 3 / 3 3 / 4 3 / 5 ... 4 / 1 4 / 2, 4 / 3, 4 / 4, 4 / 5 ... 5 / 1 5 / 2, 5 / 3, 5 / 4 5 / 5 ... ... ... Z to square our side France to the table each numbered. The first is the 1 / 1, 2 1 / 2, followed by 2 / 1, 3 / 1, 2 / 2, 1 / 3, 1 / 4, 2 / 3, 3 / 2, 4 / 1, 5 / 1, 4 / 2 ...... requirements : For a given input of the number N (0lt; Nlt; 10000), to which the output of N items. Such as : N = 7 importation; Output 1 / 4.
