给定一个句子，要求把句子中的每个单词都逆序。 简单题，找空格，然后对每个单词reverse，直接调string::reverse或者自己写都可以。 代码如下： [cpp] class Solution { public: string reverseWords(string s) { int i = 0, j = 0, n = s.size(); while (j < n) { while (j < n&&s[j] != ‘ ‘)++j; reverse(s.begin() + i, s.begin() + j); i = ++j; } return s; } }; [/cpp] 本代码提交AC，用时23MS。]]>
