Long long ago, there were $n$ adorkable GT. Divided into two groups, they were playing games together, forming a column. The $i-th$ GT would randomly get a value of ability $b_i$. At the $i-th$ second, the $i-th$ GT would annihilate GTs who are in front of him, whose group differs from his, and whose value of ability is less than his.

In order to make the game more interesting, GTW, the leader of those GTs, would emit energy for $m$ times, of which the $i-th$ time of emitting energy is $c_i$. After the $c_i$ second, $b_1, b_2,...,b_{c_i}$ would all be added 1.

GTW wanted to know how many GTs would survive after the $n-th$ second.

The first line of the input file contains an integer $T (\leq 5)$, which indicates the number of test cases.

For each test case, there are $n + m + 1$ lines in the input file.

The first line of each test case contains 2 integers $n$ and $m$, which indicate the number of GTs and the number of emitting energy, respectively.$(1\leq n,m \leq 50000)$

In the following $n$ lines, the $i-th$ line contains two integers $a_i$ and $b_i$, which indicate the group of the $i-th$ GT and his value of ability, respectively. $(0\leq a_i\leq 1, 1\leq b_i\leq 10^6)$

In the following $m$ lines, the $i-th$ line contains an integer $c_i$, which indicates the time of emitting energy for $i-th$ time.

In the following $m$ lines, the $i-th$ line contains an integer $c_i$, which indicates the time of emitting energy for $i-th$ time.

There should be exactly $T$ lines in the output file.

The $i-th$ line should contain exactly an integer, which indicates the number of GTs who survive.

The $i-th$ line should contain exactly an integer, which indicates the number of GTs who survive.
