Given an input string, reverse the string word by word.

For example,
Given s = "the sky is blue",
return "blue is sky the".

click to show clarification.

• What constitutes a word?
  A sequence of non-space characters constitutes a word.
• Could the input string contain leading or trailing spaces?
  Yes. However, your reversed string should not contain leading or trailing spaces.
• How about multiple spaces between two words?
  Reduce them to a single space in the reversed string.

题解：

 一个用了java的s.split(" ")，按空格分隔。

然后调用了系统函数：Collections.reverse(list);把list顺序调换了。

最后再把结果存成数组即可。
