import java.io.*;import java.util.*;
class Missno
{
public static void main(String arg[ ])
{
Scanner obj=new Scanner(System.in);
System.out.println("enter n value");
int n=obj.nextInt();
int sum=0;
int c,i,a[]=new int[n];;
System.out.println("enter values");
for(i=0;i<n-1;i++)
{
a[i]=obj.nextInt();
sum=sum+a[i];
}
c=(n*(n+1)/2)-sum;
System.out.println("missing no is"+c);
}
