import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import java.util.HashMap;
import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringTokenizer st = new StringTokenizer(br.readLine());

        int N = Integer.parseInt(st.nextToken());
        int M = Integer.parseInt(st.nextToken());

        HashMap<String, String> map = new HashMap<>();
        for(int i=0; i<N; i++)
        {
            st = new StringTokenizer(br.readLine());
            String site_address = st.nextToken();
            String password = st.nextToken();
            map.put(site_address, password);
        }

        StringBuilder sb = new StringBuilder();

            sb.append(map.get(site_address) + "\n");
        }

        System.out.println(sb);
    }
