代码如下：

class MagicDictionary 
{
public:MagicDictionary() {}void buildDict(vector<string> dictionary) {words=dictionary;}bool search(string searchWord) {for(const auto& word:words){if(word.size()!=searchWord.size())  {continue;}int diff=0;for(int i=0;i<word.size();i++){if(word[i]!=searchWord[i]){diff++;}}if(diff==1) {return true;}}return false;}private:vector<string> words;
};/*** Your MagicDictionary object will be instantiated and called as such:* MagicDictionary* obj = new MagicDictionary();* obj->buildDict(dictionary);* bool param_2 = obj->search(searchWord);*/
