代码说明:

码分多址是一种很有前途的技术,该技术本用来以低误码率发送多个信号。不同用户使用不同的随机产生的伪随机序列。的用来发送多用户信号的故障率低这两个数据用户在使用两个不同的伪随机序列的随机生成之一。两个用户的数据信号与伪随机序列的相乘,码被扩展并传输。接收到的扩展信号到接收端通过同样的伪随机序列被解调出来。

    我们的目的是将一个分数拆分成若干个分子是1分母是正整数的分数之和的形式。例如2/3可以拆分成1/2+1/6的形式。这里不考虑顺序,比如1/6+1/2和1/2+1/6相同。 输入p, q, a, n, 其中p/q为分数,对这个分数进行拆分,要求拆分的分数个数不能多于n个,所有分母的乘积不能大于a。求有多少种拆分方法? 输入:最多200组数据。在每行中都有四个数分别表示p, q, a, n,之间以空格隔开,并且满足p,q<=800,a<=12000,n<=7,最后以四个0做为输入的结束。 输入示例: 2 3 120 3 2 3 300 3 0 0 0 0 输出示例: 4 7 (Our aim is to split a fraction into a number of elements is a denominator is a positive integer fraction of the sum of form. For example, 2/3 can be split into 1/2+1/6 form. Not considered here, the order, such as 1/6+1/2 and 1/2+1/6 of the same. Input p, q, a, n, where p/q as a fraction of this split scores require no more than the number of split points n-all the product of the denominator can not be larger than a. How many kinds of demand split method? Input: Up to 200 sets of data. In each line has four numbers indicate the p, q, a, n, separated by a space between, and meet the p, q < = 800, a < = 12000, n < = 7, the end, four 0 as the input end. Input Example: 2,312,032,330,030,000 sample output: 47)
