题目描述

You are given an array a1,a2,,ana_1, a_2, \dots, a_n and an array b1,b2,,bnb_1, b_2, \dots, b_n .

For one operation you can sort in non-decreasing order any subarray a[lr]a[l \dots r] of the array aa .

For example, if a=[4,2,2,1,3,1]a = [4, 2, 2, 1, 3, 1] and you choose subbarray a[25]a[2 \dots 5] , then the array turns into [4,1,2,2,3,1][4, 1, 2, 2, 3, 1] .

You are asked to determine whether it is possible to obtain the array bb by applying this operation any number of times (possibly zero) to the array aa .

输入格式

The first line contains one integer tt ( 1t31051 \le t \le 3 \cdot 10^5 ) — the number of queries.

The first line of each query contains one integer nn ( 1n31051 \le n \le 3 \cdot 10^5 ).

The second line of each query contains nn integers a1,a2,,ana_1, a_2, \dots, a_n ( 1ain1 \le a_i \le n ).

The third line of each query contains nn integers b1,b2,,bnb_1, b_2, \dots, b_n ( 1bin1 \le b_i \le n ).

It is guaranteed that n3105\sum n \le 3 \cdot 10^5 over all queries in a test.

输出格式

For each query print YES (in any letter case) if it is possible to obtain an array bb and NO (in any letter case) otherwise.

说明/提示

In first test case the can sort subarray a1a5a_1 \dots a_5 , then aa will turn into [1,1,4,4,7,5,6][1, 1, 4, 4, 7, 5, 6] , and then sort subarray a5a6a_5 \dots a_6 .
