B. Digits
math; number theory
Artem wrote the digit \(d\) on the board exactly \(n!\) times in a row. So, he got the number \(dddddd \dots ddd\) (exactly \(n!\) digits).Now he is curious about which odd digits from \(1\) to \(9\) divide the number written on the board.
The first line contains a single integer \(t\) (\(1 \le t \le 100\)) — the number of test cases. The next \(t\) test cases follow.Each test case consists of a single line containing two integers \(n\) and \(d\) (\(2 \le n \le 10^9\), \(1 \le d \le 9\)).
For each test case, output the odd digits in ascending order that divide the number written on the board.
The factorial of a positive integer \(n\) (\(n!\)) is the product of all integers from \(1\) to \(n\). For example, the factorial of \(5\) is \(1 \cdot 2 \cdot 3 \cdot 4 \cdot 5 = 120\).
