Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert)

import java. util. Scanner;

public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}

public static void main (String [] args) {

System. out. println("Testing started");
System. out. println("2, expecting 8, got: " + cubeNum(2));

/* Your solution goes here */

System. out. println("Testing completed");

return;
}
}
