A sign function is simple, its gets a number and tells you if its positive, negative or zero.

for example :

sign(5) => 1

sign(-30)=> -1

sign(0) => 0 sign gets an int parameter.

print out 1,-1 or 0 depending on the input

import java.util.*;

class Main {

public static void main(String[] args) { Scanner inp = new Scanner(System.in); int n = inp.nextInt();

System.out.println(sign(n)); }

public static int sign(int n) { //your code here }//end sign

}
