Problem Statement

Cherry calculation is a technique used when adding two positive integers whose sum is a $2$-digit integer: one of the positive integers is split into $2$ positive integers, and the associative law is used to make $10$ appear in the calculation process, which makes the calculation easier.

For example, consider a calculation such as $5+9= 5+(5+4) = 10+4 = 14$.

You are given single-digit positive integers $A,B$. Here, it is guaranteed that $A+B \ge 11$.

Split $B$ so that the cherry calculation works. More strictly, find the pair of positive integers $x,y$ that satisfies all of the following conditions.

• $A+x=10$
• $x+y = B$

Under the constraints, such a pair $x,y$ is uniquely determined.

Input

$A\ B$

Constraints

• $2\le A,B \le 9$
• $A+B\ge 11$
• All inputs are integers.

Output

Print $x,y$ satisfying the conditions in this order on one line, separated by a space, followed by a newline.
