In the main method, place plus and minus signs correctly so that the variable result is equal to 20. Signs must be placed only in the line where the variable result is declared. Do not change the order of the variables in this line. Each variable must be preceded by either a plus or minus sign.

package com.codegym.task.task01.task0137; /* Only 20 will do */ public class Solution { public static int a = 1; public static int b = 3; public static int c = 9; public static int d = 27; public static void main(String[] args) { int result = - a - b - c - d; System.out.println(result); } }
