题目描述

Multiset —is a set of numbers in which there can be equal elements, and the order of the numbers does not matter. Two multisets are equal when each value occurs the same number of times. For example, the multisets {2,2,4}\{2,2,4\} and {2,4,2}\{2,4,2\} are equal, but the multisets {1,2,2}\{1,2,2\} and {1,1,2}\{1,1,2\} — are not.

You are given two multisets aa and bb , each consisting of nn integers.

In a single operation, any element of the bb multiset can be doubled or halved (rounded down). In other words, you have one of the following operations available for an element xx of the bb multiset:

  • replace xx with x2x \cdot 2 ,
  • or replace xx with x2\lfloor \frac{x}{2} \rfloor (round down).

Note that you cannot change the elements of the aa multiset.

See if you can make the multiset bb become equal to the multiset aa in an arbitrary number of operations (maybe 00 ).

For example, if n=4n = 4 , a={4,24,5,2}a = \{4, 24, 5, 2\} , b={4,1,6,11}b = \{4, 1, 6, 11\} , then the answer is yes. We can proceed as follows:

  • Replace 11 with 12=21 \cdot 2 = 2 . We get b={4,2,6,11}b = \{4, 2, 6, 11\} .
  • Replace 1111 with 112=5\lfloor \frac{11}{2} \rfloor = 5 . We get b={4,2,6,5}b = \{4, 2, 6, 5\} .
  • Replace 66 with 62=126 \cdot 2 = 12 . We get b={4,2,12,5}b = \{4, 2, 12, 5\} .
  • Replace 1212 with 122=2412 \cdot 2 = 24 . We get b={4,2,24,5}b = \{4, 2, 24, 5\} .
  • Got equal multisets a={4,24,5,2}a = \{4, 24, 5, 2\} and b={4,2,24,5}b = \{4, 2, 24, 5\} .

输入格式

The first line of input data contains a single integer tt ( 1t1041 \le t \le 10^4 ) —the number of test cases.

Each test case consists of three lines.

The first line of the test case contains an integer nn ( 1n21051 \le n \le 2 \cdot 10^5 ) —the number of elements in the multisets aa and bb .

The second line gives nn integers: a1,a2,,ana_1, a_2, \dots, a_n ( 1a1a2an1091 \le a_1 \le a_2 \le \dots \le a_n \le 10^9 ) —the elements of the multiset aa . Note that the elements may be equal.

The third line contains nn integers: b1,b2,,bnb_1, b_2, \dots, b_n ( 1b1b2bn1091 \le b_1 \le b_2 \le \dots \le b_n \le 10^9 ) — elements of the multiset bb . Note that the elements may be equal.

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

输出格式

For each test case, print on a separate line:

  • YES if you can make the multiset bb become equal to aa ,
  • NO otherwise.

You can output YES and NO in any case (for example, strings yEs, yes, Yes and YES will be recognized as positive answer).

说明/提示

The first example is explained in the statement.

In the second example, it is impossible to get the value 3131 from the numbers of the multiset bb by available operations.

In the third example, we can proceed as follows:

  • Replace 22 with 22=42 \cdot 2 = 4 . We get b={4,14,14,26,42}b = \{4, 14, 14, 26, 42\} .
  • Replace 1414 with 142=7\lfloor \frac{14}{2} \rfloor = 7 . We get b={4,7,14,26,42}b = \{4, 7, 14, 26, 42\} .
  • Replace 2626 with 262=13\lfloor \frac{26}{2} \rfloor = 13 . We get b={4,7,14,13,42}b = \{4, 7, 14, 13, 42\} .
  • Replace 4242 with 422=21\lfloor \frac{42}{2} \rfloor = 21 . We get b={4,7,14,13,21}b = \{4, 7, 14, 13, 21\} .
  • Replace 2121 with 212=10\lfloor \frac{21}{2} \rfloor = 10 . We get b={4,7,14,13,10}b = \{4, 7, 14, 13, 10\} .
  • Got equal multisets a={4,7,10,13,14}a = \{4, 7, 10, 13, 14\} and b={4,7,14,13,10}b = \{4, 7, 14, 13, 10\} .
