A set of positive integers $S$ is called beautiful if, for every two integers $x$ and $y$ from this set, either $x$ divides $y$ or $y$ divides $x$ (or both).

You are given two integers $l$ and $r$. Consider all beautiful sets consisting of integers not less than $l$ and not greater than $r$. You have to print two numbers:

• the maximum possible size of a beautiful set where all elements are from $l$ to $r$;
• the number of beautiful sets consisting of integers from $l$ to $r$ with the maximum possible size.

Since the second number can be very large, print it modulo $998244353$.

The first line contains one integer $t$ ($1 \le t \le 2 \cdot 10^4$) — the number of test cases.

Each test case consists of one line containing two integers $l$ and $r$ ($1 \le l \le r \le 10^6$).

For each test case, print two integers — the maximum possible size of a beautiful set consisting of integers from $l$ to $r$, and the number of such sets with maximum possible size. Since the second number can be very large, print it modulo $998244353$.
