import java.util.*;
public class Main
{
   static Iterator func(ArrayList mylist)
   {
      Iterator it=mylist.iterator();
      while(it.hasNext())
      {
         Object element = it.next();
         if(element instanceof String)//Hints: use instanceof operator
            break;
      }
      return it;
      
   }

   public static void main(String []argh)
   {
      ArrayList mylist = new ArrayList();
      Scanner sc=new Scanner(System.in);
      int n=sc.nextInt();
      int m=sc.nextInt();
      for(int i=0;i<n;i++)
      {
         mylist.add(sc.nextInt());
      }
      mylist.add("###");
      for(int i=0;i<m;i++)
