试题地址：https://leetcode-cn.com/problems/reverse-words-in-a-string/

试题思路：

go自带strings.Fields()函数，可以剔除多余空格

试题代码：

func reverseWords(s string) string {
    strList := strings.Fields(s)
    if len(strList) == 0 {
        return ""
    }
    reverseS := ""
    for i := len(strList) - 1; i > 0; i-- {
        reverseS += strList[i] + " "
    }
    reverseS += strList[0]

    return reverseS
}
