	{
		// 整数の入力
		//int a = int.Parse(Console.ReadLine());
		// スペース区切りの整数の入力
		//string[] input = Console.ReadLine().Split(' ');
		//int b = int.Parse(input[0]);
		//int c = int.Parse(input[1]);
		// 文字列の入力
		//string s = Console.ReadLine();
		//出力
		//Console.WriteLine((a+b+c) + " " + s);
      string S = Console.ReadLine();
      string T = Console.ReadLine();
      
      Console.WriteLine(S+T);
