Problem Statement
Y-kun, having failed in love, is scheming to make people unhappy by erasing $7$ from the integers.
You are given a non-negative integer $N$ that contains $7$ in at least one of its digits.
Find integers $A,B$ such that $A+B=N$ and neither of them contains $7$ in any digit.
If there are multiple solutions, you may output any of them.
Input
$N$
A non-negative integer $N$ is given.
- $0 \le N \le 10^9$
- At least one digit of $N$ is $7$
Output
$A$ $B$
Output integers $A,B$ satisfying the conditions of the problem, separated by a space.
If no solution exists, output $-1$.
Print a newline at the end.
- $-10^9 \le A \le 10^9$
- $-10^9 \le B \le 10^9$
