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);
