Problem Statement
翻译中…
You are given sequences of positive integers of length $N$: $A=(A_1,A_2,\dots,A_N)$ and $B=(B_1,B_2,\dots,B_N)$.
翻译中…
You can repeat the following operation any number of times (possibly zero).
翻译中…
- Choose an integer
$i$such that$1 \le i \le N$and replace$A_i$with$A_{i+1}$.
翻译中…
Here, regard $A_{N+1}$ as $A_1$.
翻译中…
Determine whether it is possible to make $A$ equal $B$.
翻译中…
You have $T$ test cases to solve.

Constraints

$1 \le T \le 5000$$1 \le N \le 5000$$1 \le A_i,B_i \le N$- For each input file, the sum of
$N$over all test cases does not exceed$5000$.

Output
翻译中…
Print $T$ lines. The $i$-th line should contain Yes if it is possible to make $A$ equal $B$ in the $i$-th test case, and No otherwise.

In the first test case, you can make $A$ equal $B$ as follows.
- Choose $i=1$ to replace $A_1$ with $A_2$, making $A=(2,2)$.
In the second test case, you can make $A$ equal $B$ as follows.
- Choose $i=4$ to replace $A_4$ with $A_1$, making $A=(2,3,1,2)$.
- Choose $i=2$ to replace $A_2$ with $A_3$, making $A=(2,1,1,2)$.
In the third test case, there is no way to make $A$ equal $B$.
