import java.util.*;
public class Q1 
{public static void main(String args[]) 
{Scanner in = new Scanner(System.in); 
int a, b, c, max;
System.out.printIn("Enter the three numbers"); 
System.out.println("Enter positive/negative numbers only"); 
a = in.nextInt(); 
b = in.nextInt(); 
c = in.nextInt(); 
if (a == b && b == c) 
System.out.printIn("The numbers are equal"); 
else 
{max = (a > b && a > c) ? a : (b > c ? b : c); 
System.out.printIn("The numbers are unequal, the greatest number is "+ max); 

if (a < 0 && b < 0 && c < 0) 
System.out.printin("All negative"); 
else if (a > 0 && b > 0 && c > 0) 
System.out.println("All positive"); 
else 
System.out.printIn("The combination of positive and negative numbers"); 
}
