Problem Description

Princess Alisha invites her friends to come to her birthday party. Each of her friends will bring a gift of some value
v,
and all of them will come at a different time. Because the lobby is not large enough, Alisha can only let a few people in at a time. She decides to let the person whose gift has the highest value enter first.



Each time when Alisha opens the door, she can decide to let
p
people enter her castle. If there are less than p
people in the lobby, then all of them would enter. And after all of her friends has arrived, Alisha will open the door again and this time every friend who has not entered yet would enter.



If there are two friends who bring gifts of the same value, then the one who comes first should enter first. Given a query
n
Please tell Alisha who the n−th
person to enter her castle is.

 

Input

The first line of the input gives the number of test cases,
T
, where 1≤T≤15.



In each test case, the first line contains three numbers
k,m
and q
separated by blanks. k
is the number of her friends invited where 1≤k≤150,000.
The door would open m times before all Alisha’s friends arrive where
0≤m≤k.
Alisha will have q
queries where 1≤q≤100.



The i−th
of the following k
lines gives a string Bi,
which consists of no more than 200
English characters, and an integer vi,
1≤vi≤108,
separated by a blank. Bi
is the name of the i−th
person coming to Alisha’s party and Bi brings a gift of value
vi.



Each of the following m
lines contains two integers t(1≤t≤k)
and p(0≤p≤k)
separated by a blank. The door will open right after the
t−th
person arrives, and Alisha will let p
friends enter her castle.



The last line of each test case will contain q
numbers n1,...,nq
separated by a space, which means Alisha wants to know who are the
n1−th,...,nq−th
friends to enter her castle.



Note: there will be at most two test cases containing
n>10000.

 

Output

For each test case, output the corresponding name of Alisha’s query, separated by a space.

优先队列+模拟,en，应该还行，时间上应该不会超时了，但是下面问题来了。。。

真的是无力吐槽了，感觉。。。

因为排序的问题，一直错，一直错，一直错，结果拖累的小组最后这个题都没A掉。。。

增加一个排序就好了，但是好像还是模拟的有点问题，因为还有一个排序啊，这样就很慢了，所以应该用数组记录下来，遍历模拟。。。
