Multiply two numbers without using loops or multiplication or division

We can implement this by using recursive operation.

public static int multiply(int x, int y) {
  if (y == 0)
   return 0;
  
  // if y is positive,Add x one by one
  if (y > 0)
   return (x + multiply(x, y - 1));
  else
   return -multiply(x, -y);
 }
