Problem Description

Long long ago, there were nn 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 mm 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.

Input

The first line of the input file contains an integerT(≤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 nn and mm, which indicate the number of GTs and the number of emitting energy, respectively.(1≤n,m≤50000)

In the following nn 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≤a​i​​≤1,1≤b​i​​≤10^​6​​)

In the following mm lines, the i−th line contains an integer c​i​​, which indicates the time of emitting energy for i−th time.

Output

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.

Hint

After the first seconds,b​1​​=4,b​2​​=2,b​3​​=3,b​4​​=1 After the second seconds,b​1​​=4,b​2​​=2,b​3​​=3,b​4​​=1 After the third seconds,b​1​​=5,b​2​​=3,b​3​​=4,b​4​​=1,and the second GT is annihilated by the third one. After the fourth seconds,b​1​​=6,b​2​​=4,b​3​​=5,b​4​​=2 c​i​​ is unordered.

问题描述

从前，有nn只萌萌的GT，他们分成了两组在一起玩游戏。他们会排列成一排，第i只GT会随机得到一个能力值b​i​​。在第i秒的时候，第i只GT可以消灭掉所有排在他前面的和他不是同一组的且能力值小于他的GT。
为了使游戏更加有趣，GT的首领GTW会发功mm次，第ii次发功的时间为c​i​​，则在第c​i​​秒结束后，b​1​​,b​2​​,...,b​c​i​​​​都会增加1。
现在，GTW想知道在第nn秒之后，会有几只GT存活下来。

输入描述

第一行只有一个整数T(T≤5)，表示测试数据组数。
第二行有两个整数n,m。表示GT的个数和GTW发功的次数。( 500001≤n≤50000,1≤m≤50000)
第三到n+2行，每行有两个整数a​i​​,b​i​​，表示第ii只GT在哪个组和他的能力值 (0≤a[i]≤1,1≤b[i]≤10​6​​)
第n+3行到第n+m+2行，每行有一个整数c​i​​,表示GTW第i次发功的时间。 1≤c[i]≤n

输出描述

总共T行，第i行表示第i组数据中，GT存活的个数。

Hint

第1秒后 能力值为4 2 3 1
第2秒后 能力值为4 2 3 1
第3秒后 能力值为5 3 4 1，第2只GT被第3只GT消灭掉了
第4秒后 能力值为6 4 5 2
c​i​​并不是有序的
我们先通过题意先计算出最后他们有多少能力值，然后，我们用两个容器分别装他们，如果可以干掉，就把它删除，然后就两个容器大小之和就好
