Practice does make perfect! You have finally achieved proficiency at the task of adding two small nonzero integers and to compute their sum . Before you move on to studying four-digit numbers, you want to achieve mastery by also understanding the inverse problem: given integer , determine nonzero and such that . None of the numbers may use more than digits.

Explanation of Sample Input 1
On input , the output is correct because . Note that many other outputs would also be correct, such as , , or even . On the other hand, the answer would be (because ), and so would (because both and must be nonzero) and (because both and must have at most three digits.)
