There is a nested loop, though. Within the first loop, a function call is made to getDivisors() which enters a second loop. It's more readable by being placed into its own function, though.

I always thought this kind of problem would require a nested loop. But your approach gave me a new perspective. What a nice representation of functional programming.

Hi can you explicate me this code please ?

Very beautiful statute.

I don't think there's a more efficient way than this.

Maybe marginally better if you skip prime numbers.

nice solution ! Is there any chance not to make iteration through all elements of array ?

Why is the direct + space and join (' ') different?

练英语咯， 多看就看懂了；

都是些奇技淫巧，书上一般没有

看了。答案。我哭晕在厕所。。。。。默默滚去看书学习
方法好多啊

做这种代码高尔夫，每一个字符都要计较，尤其是字符限制比较严格的。

我这一系列的还算是限制比较宽松的，一般都是我能精简出来的代码长度加上5到10字符

往往可以看到比限制字符少很多的答案，高手在民间。。。

我次奥！！
我怎么没想到！！
哔了狗了。多谢大神！！妈个鸡！！居然是这样的子的！！！
