( 15858 ) A Forgetting Things PROGRAMMING math 900

B'Kolya is very absent-minded. Today his math teacher asked him to solve a simple problem with the equation a + 1 = b with positive integers a and b , but Kolya forgot the numbers a and b . He does, however, remember that the first (leftmost) digit of a was d_a , and the first (leftmost) digit of b was d_b . Can you reconstruct any equation a + 1 = b that satisfies this property? It may be possible that Kolya misremembers the digits, and there is no suitable equation, in which case report so. The only line contains two space-separated digits d_a and d_b ( 1 <= q d_a, d_b <= q 9 ). If there is no equation a + 1 = b with positive integers a and b such that the first digit of a is d_a , and the first digit of b is d_b , print a single number -1 . Otherwise, print any suitable a and b that both are positive and do not exceed 10^9 . It is guaranteed that if a solution exists, there also exists a solution with both numbers not exceeding 10^9 .
