Problem Statement
Kenus, the organizer of International Euclidean Olympiad, is seeking a pair of two integers that requires many steps to find its greatest common divisor using the Euclidean algorithm.
You are given $Q$ queries. The $i$-th query is represented as a pair of two integers $X_i$ and $Y_i$, and asks you the following: among all pairs of two integers $(x,y)$ such that $1 ≤ x ≤ X_i$ and $1 ≤ y ≤ Y_i$, find the maximum Euclidean step count (defined below), and how many pairs have the maximum step count, modulo $10^9+7$.
Process all the queries. Here, the Euclidean step count of a pair of two non-negative integers $(a,b)$ is defined as follows:
$(a,b)$and$(b,a)$have the same Euclidean step count.$(0,a)$has a Euclidean step count of$0$.- If
$a > 0$and$a ≤ b$, let$p$and$q$be a unique pair of integers such that$b=pa+q$and$0 ≤ q < a$. Then, the Euclidean step count of$(a,b)$is the Euclidean step count of$(q,a)$plus$1$.
Constraints
$1 ≤ Q ≤ 3 × 10^5$$1 ≤ X_i,Y_i ≤ 10^{18}(1 ≤ i ≤ Q)$
Input
The input is given from Standard Input in the following format:
Q
X_1 Y_1
:
X_Q Y_Q
Output
For each query, print the maximum Euclidean step count, and the number of the pairs that have the maximum step count, modulo $10^9+7$, with a space in between.
