輸入描述:

先輸入字典中單詞的個數，再輸入n個單詞作為字典單詞。 輸入一個單詞，查詢其在字典中兄弟單詞的個數 再輸入數字n

輸出描述:

根據輸入，輸出查詢到的兄弟單詞的個數

示例1

輸入

3 abc bca cab abc 1

輸出

2 bca

程式碼如下

//Q26查詢兄弟單詞
class Dic
{
public:

};
int Q26BrotherWordsFind()
{
	
	int n = 0;
	while(cin >> n)
	{
		vector<string> vecstr;
		string str;
		for(unsigned int i = 0; i < n; i++)
		{
			cin>>str;
			vecstr.push_back(str);
		}
		string goal;
		cin >> goal;
		int k = 0; 
		cin >> k;
		vector<string> brostr;
		sort(vecstr.begin(),vecstr.end());
		for (unsigned int i = 0; i < vecstr.size(); i++)
		{
			if(goal.size() != vecstr[i].size())
				continue;
			if(goal == vecstr[i])
				continue;
			string sgoal = goal;
			string sstr  = vecstr[i];
			sort(sgoal.begin(),sgoal.end());
			sort(sstr.begin(),sstr.end());
			if(sstr == sgoal)
				brostr.push_back(vecstr[i]);
		}
		cout << brostr.size();
		if(k < brostr.size())
			cout << " " << brostr[k];
		cout << endl;
	}
	return 0;
