Noblesse Code

You will be given $n$ noblesse code pairs $(a_1,b_1),(a_2,b_2),\dots,(a_n,b_n)$ and $q$ queries. In each query, you will be given a pair $(A,B)$, you need to figure out how many noblesse code pairs can be transformed from the given pair $(A,B)$. Every time you can transform the current pair $(A,B)$ into $(A+B,B)$ or $(A,A+B)$. You can do the transform operation for arbitrary times (or do nothing).

The first line contains a single integer $T$ ($1 \leq T \leq 100$), the number of test cases. For each test case:

The first line of the input contains two integers $n$ and $q$ ($1 \leq n,q \leq 50\,000$), denoting the number of noblesse code pairs and the number of queries.

In the next $n$ lines, the $i$-th line contains two integers $a_i$ and $b_i$ ($1\leq a_i,b_i\leq 10^{18}$), describing the $i$-th noblesse code pair.

In the next $q$ lines, the $i$-th line contains two integers $A$ and $B$ ($1\leq A,B\leq 10^{18}$), describing the pair in the $i$-th query.

It is guaranteed that the sum of all $n$ is at most $500\,000$, and the sum of all $q$ is at most $500\,000$.

For each query, print a single line containing an integer, denoting the number of noblesse code pairs that can be transformed from the given pair. Note that two noblesse code pairs $(a_i,b_i),(a_j,b_j)$ are considered to be different if and only if $i\neq j$.
