Crack of one of Rohan Jhunjhunwala's submissions.

class y{public static void main(String[]b){int n=2,l=870119,i,f,j;i=new java.util.Scanner(System.in).nextInt();while(i>0){f=0;for(j=1;j<l;j++){if(n%j==0){f++;}}if(f==2){System.out.println(n);i--;}n++;}}}

The spec said it only needs to work up to the 2^16-1 = 65535th prime (821603).
We can remove the string x="z...z" and the loop to increment this value and set l to be a working value greater than or equal to 821603. In removing that we can also remove the initialisation of i, so we get ne numeric characters 0791819 to use. The smallest valid, working value for l is now 870119.
