My code is not passing the test case

#1

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int N = sc.nextInt();

	if(N>2){
		int i=2;
	    while(i<N){
		    if(N%i==0){
			    System.out.println("Not Prime");
		
		}
		    else {
			    System.out.println("Prime");
		}
		i++;
		}
}
	

}

}

@mishikasrvastava,
You can further optimize your code.

If you think about it then all factors of a number will be less than N/2. There’s a way to further optimize it by going till sqrt(N). Try to find the logic why sqrt(N) will work, if you face any problem, reply on this thread. :slight_smile:
