The well-known Fibonacci sequence $$$F_0, F_1, F_2,\ldots $$$ is defined as follows:
Given an increasing arithmetic sequence of positive integers with $$$n$$$ elements: $$$(a, a + d, a + 2\cdot d,\ldots, a + (n - 1)\cdot d)$$$.
You need to find another increasing arithmetic sequence of positive integers with $$$n$$$ elements $$$(b, b + e, b + 2\cdot e,\ldots, b + (n - 1)\cdot e)$$$ such that:
The first line contains three positive integers $$$n$$$, $$$a$$$, $$$d$$$ ($$$1 \leq n, a, d, a + (n - 1) \cdot d < 10^6$$$).
If no such arithmetic sequence exists, print $$$-1$$$.
Otherwise, print two integers $$$b$$$ and $$$e$$$, separated by space in a single line ($$$0 < b, e < 2^{64}$$$).
If there are many answers, you can output any of them.
3 1 1
2 1
5 1 2
19 5
In the first test case, we can choose $$$(b, e) = (2, 1)$$$, because $$$F_2 = 1, F_3 = 2, F_4 = 3$$$.
In the second test case, we can choose $$$(b, e) = (19, 5)$$$ because:
