<----------------- Import appropriate pkgs ------------->

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

System.out.println("Enter the no of nos");
int n=Integer.parseInt(br.readLine());
int[] a= new int[n];
System.out.println("Enter the nos");
for(int i=0;i<n;i++)
{
a[i]=Integer.parseInt(br.readLine());
}
Arrays.sort(a);

LOOP: for(int i=n-1;i>=0;i--)
{
int b=2;
boolean c=true;
while(b<a[i])
{
if((a[i]%b)==0)
{
c=false;
continue LOOP;
}
b++;
}
if(c)
{
System.out.println("The largest prime no among the
list is "+a[i]);
break;
}

}
}
}
