For example, Given s = "the sky is blue", return "blue is sky the". 解析:将字符串中的单词逆序输出 借助一个堆栈,从前向后遍历字符串,遇到空,跳过,直到非空字符,拼接word,等再次遇到空时,得到一个word,加入堆栈, 以此类推,直到遍历到s的最后一个字符为止。 最后,将堆栈中的word依次输出 java编码:...
A word is defined as a sequence of non-space characters. Input string may contain leading or trailing spaces. However, your reversed string should not contain leading or trailing spaces. You need to reduce multiple spaces between two words to a single space in the reversed string. Follow up:...
