Sanae and Giant Robot
Is it really?! The robot only existing in my imagination?! The Colossal Walking Robot?!!— Kochiya Sanae Sanae made a giant robot — Hisoutensoku, but something is wrong with it. To make matters worse, Sanae can not figure out how to stop it, and she is forced to fix it on-the-fly.The state of a robot can be represented by an array of integers of length $$$n$$$. Initially, the robot is at state $$$a$$$. She wishes to turn it into state $$$b$$$. As a great programmer, Sanae knows the art of copy-and-paste. In one operation, she can choose some segment from given segments, copy the segment from $$$b$$$ and paste it into the same place of the robot, replacing the original state there. However, she has to ensure that the sum of $$$a$$$ does not change after each copy operation in case the robot go haywire. Formally, Sanae can choose segment $$$[l,r]$$$ and assign $$$a_i = b_i$$$ ($$$l\le i\le r$$$) if $$$\sum\limits_{i=1}^n a_i$$$ does not change after the operation.Determine whether it is possible for Sanae to successfully turn the robot from the initial state $$$a$$$ to the desired state $$$b$$$ with any (possibly, zero) operations.
Test case 1:One possible way of turning $$$a$$$ to $$$b$$$:First, select $$$[1,3]$$$. After the operation, $$$a=[3,2,5,2,3]$$$.Then, select $$$[2,5]$$$. After the operation, $$$a=[3,2,5,4,1]=b$$$.Test case 2:It can be shown that it is impossible to turn $$$a$$$ into $$$b$$$. 
Each test contains multiple test cases. The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 2\cdot 10^4$$$) — the number of test cases. The descriptions of the test cases follow.The first line of each test case contains two integers $$$n$$$, $$$m$$$ ($$$2 \leq n\leq 2\cdot 10^5$$$, $$$1 \leq m\leq 2\cdot 10^5$$$) — the length of $$$a$$$, $$$b$$$ and the number of segments.The second line contains $$$n$$$ intergers $$$a_1,a_2,\ldots,a_n$$$ ($$$1 \leq a_i \leq 10^9$$$) — the initial state $$$a$$$.The third line contains $$$n$$$ intergers $$$b_1,b_2,\ldots,b_n$$$ ($$$1 \leq b_i \leq 10^9$$$) — the desired state $$$b$$$.Then $$$m$$$ lines follow, the $$$i$$$-th line contains two intergers $$$l_i,r_i$$$ ($$$1 \leq l_i < r_i \leq n$$$) — the segments that can be copy-pasted by Sanae.It is guaranteed that both the sum of $$$n$$$ and the sum of $$$m$$$ over all test cases does not exceed $$$2 \cdot 10 ^ 5$$$.
For each test case, print "YES" (without quotes) if $$$a$$$ can be turned into $$$b$$$, or "NO" (without quotes) otherwise.You can output "YES" and "NO" in any case (for example, strings "yEs", "yes" and "Yes" will be recognized as a positive response).
