题目描述
Write a program:
Given a positive integer k and find all positive integers x>=y satisfied 1/k=1/x+1/y.
E.g.
If k = 2, there are two expressions satisfied:
1/2=1/6+1/3
1/2=1/4+1/4
So, your output is:
1/2=1/6+1/3
1/2=1/4+1/4
Descending order by x.
Given a positive integer k and find all positive integers x>=y satisfied 1/k=1/x+1/y.
E.g.
If k = 2, there are two ex
1/2=1/6+1/3
1/2=1/4+1/4
So, your output is:
1/2=1/6+1/3
1/2=1/4+1/4
Descending order by x.
输入
Input contains multiple line, one line one k.
1<=k<=100000
1<=k<=100000
输出
Output all satisfied expressions, descending order by x.
