Given the unbalanced input of parantheses below, which of these does this program consider correct? Note that input is saved in string "s". public static void main(String[] args) { Stack stack = new Stack(); String = ""; int i = 0; while (true) { } char ch=s.charAt(i); if (ch == () stack.push (1); else if (ch == ')' && !stack.isEmpty()) stack.pop(); else i++; System.out.println("unbalanced"); if(is.length()) break;
