CF1365F Swaps Again

Ayush, Ashish and Vivek are busy preparing a new problem for the next Codeforces round and need help checking if their test cases are valid. Each test case consists of an integer $ n $ and two arrays $ a $ and $ b $ , of size $ n $ . If after some (possibly zero) operations described below, array $ a $ can be transformed into array $ b $ , the input is said to be valid. Otherwise, it is invalid. An operation on array $ a $ is: - select an integer $ k $ $ (1 \le k \le \lfloor\frac{n}{2}\rfloor) $ - swap the prefix of length $ k $ with the suffix of length $ k $ For example, if array $ a $ initially is $ \{1, 2, 3, 4, 5, 6\} $ , after performing an operation with $ k = 2 $ , it is transformed into $ \{5, 6, 3, 4, 1, 2\} $ . Given the set of test cases, help them determine if each one is valid or invalid.

The first line contains one integer $ t $ $ (1 \le t \le 500) $ — the number of test cases. The description of each test case is as follows. The first line of each test case contains a single integer $ n $ $ (1 \le n \le 500) $ — the size of the arrays. The second line of each test case contains $ n $ integers $ a_1 $ , $ a_2 $ , ..., $ a_n $ $ (1 \le a_i \le 10^9) $ — elements of array $ a $ . The third line of each test case contains $ n $ integers $ b_1 $ , $ b_2 $ , ..., $ b_n $ $ (1 \le b_i \le 10^9) $ — elements of array $ b $ .

For each test case, print "Yes" if the given input is valid. Otherwise print "No". You may print the answer in any case.

For the first test case, we can swap prefix $ a[1:1] $ with suffix $ a[2:2] $ to get $ a=[2, 1] $ . For the second test case, $ a $ is already equal to $ b $ . For the third test case, it is impossible since we cannot obtain $ 3 $ in $ a $ . For the fourth test case, we can first swap prefix $ a[1:1] $ with suffix $ a[4:4] $ to obtain $ a=[2, 2, 3, 1] $ . Now we can swap prefix $ a[1:2] $ with suffix $ a[3:4] $ to obtain $ a=[3, 1, 2, 2] $ . For the fifth test case, it is impossible to convert $ a $ to $ b $ .
