	public void run() {
		try {
			in = new Scanner(new FileReader("input.txt"));
			out = new PrintWriter(System.out);
			int n, m, i;
			String str;
			while (in.hasNextInt()) {
				n = in.nextInt();
				m = in.nextInt();
				//out.println(n + " and " + m);
				in.nextLine();
				for (i = 0; i < m; i++) {
					str = in.nextLine();
					if (i == (n - 1) % m) out.println(str);
				}
			}
			in.close();
			out.close();
		}
		catch (Exception ex) {
			ex.printStackTrace();
			System.exit(-1);
		}
	}
	
	public static void main(String args[]) {
		new Thread(new Solution()).start();
	}
