题目描述

Boris thinks that chess is a tedious game. So he left his tournament early and went to a barber shop as his hair was a bit messy.

His current hair can be described by an array a1,a2,,ana_1,a_2,\ldots, a_n , where aia_i is the height of the hair standing at position ii . His desired haircut can be described by an array b1,b2,,bnb_1,b_2,\ldots, b_n in a similar fashion.

The barber has mm razors. Each has its own size and can be used at most once. In one operation, he chooses a razor and cuts a segment of Boris's hair. More formally, an operation is:

  • Choose any razor which hasn't been used before, let its size be xx ;
  • Choose a segment [l,r][l,r] ( 1lrn1\leq l \leq r \leq n );
  • Set ai:=min(ai,x)a_i := \min (a_i,x) for each lirl\leq i \leq r ;

Notice that some razors might have equal sizes — the barber can choose some size xx only as many times as the number of razors with size xx .

He may perform as many operations as he wants, as long as any razor is used at most once and ai=bia_i = b_i for each 1in1 \leq i \leq n at the end. He does not have to use all razors.

Can you determine whether the barber can give Boris his desired haircut?

输入格式

Each test contains multiple test cases. The first line contains the number of test cases tt ( 1t200001 \leq t \leq 20\,000 ). The description of the test cases follows.

The first line of each test case contains a positive integer nn ( 3n21053\leq n\leq 2\cdot 10^5 ) — the length of arrays aa and bb .

The second line of each test case contains nn positive integers a1,a2,,ana_1, a_2, \ldots, a_n ( 1ai1091 \leq a_i \leq 10^9 ) — Boris's current hair.

The third line of each test case contains nn positive integers b1,b2,,bnb_1, b_2, \ldots, b_n ( 1bi1091 \leq b_i \leq 10^9 ) — Boris's desired hair.

The fourth line of each test case contains a positive integer mm ( 1m21051 \leq m \leq 2\cdot 10^5 ) — the number of razors.

The fifth line of each test case contains mm positive integers x1,x2,,xmx_1,x_2, \ldots, x_m ( 1xi1091 \leq x_i \leq 10^9 ) — the sizes of the razors.

It is guaranteed that the sum of nn and the sum of mm over all test cases do not exceed 21052\cdot 10^5 .

输出格式

For each test case, print "YES" if the barber can cut Boris's hair as desired. Otherwise, print "NO".

You can output the answer in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.

说明/提示

In the first test case, Boris's hair is initially [3,3,3][3,3,3] . Let us describe a sequence of 22 operations the barber can perform:

  • The barber uses the razor with size 11 on the segment [2,2][2,2] ; hence Boris's hair becomes [3,1,3][3,1,3] .
  • The barber uses the razor with size 22 on the segment [1,3][1,3] ; hence Boris's hair becomes [2,1,2][2,1,2] which is the desired haircut.

In the third test case, no operation has to be done since Boris's hair is already as desired.

In the fourth test case, no cuts will be able to increase the third element in [1,1,1][1,1,1] in a way that the array becomes [1,1,2][1,1,2] .
