Shinju loves permutations very much! Today, she has borrowed a permutation $$$p$$$ from Juju to play with.

The $$$i$$$-th cyclic shift of a permutation $$$p$$$ is a transformation on the permutation such that $$$p = [p_1, p_2, \ldots, p_n] $$$ will now become $$$ p = [p_{n-i+1}, \ldots, p_n, p_1,p_2, \ldots, p_{n-i}]$$$.

Let's define the power of permutation $$$p$$$ as the number of distinct elements in the prefix maximums array $$$b$$$ of the permutation. The prefix maximums array $$$b$$$ is the array of length $$$n$$$ such that $$$b_i = \max(p_1, p_2, \ldots, p_i)$$$. For example, the power of $$$[1, 2, 5, 4, 6, 3]$$$ is $$$4$$$ since $$$b=[1,2,5,5,6,6]$$$ and there are $$$4$$$ distinct elements in $$$b$$$.

Unfortunately, Shinju has lost the permutation $$$p$$$! The only information she remembers is an array $$$c$$$, where $$$c_i$$$ is the power of the $$$(i-1)$$$-th cyclic shift of the permutation $$$p$$$. She's also not confident that she remembers it correctly, so she wants to know if her memory is good enough.

Given the array $$$c$$$, determine if there exists a permutation $$$p$$$ that is consistent with $$$c$$$. You do not have to construct the permutation $$$p$$$.

A permutation is an array consisting of $$$n$$$ distinct integers from $$$1$$$ to $$$n$$$ in arbitrary order. For example, $$$[2,3,1,5,4]$$$ is a permutation, but $$$[1,2,2]$$$ is not a permutation ($$$2$$$ appears twice in the array) and $$$[1,3, 4]$$$ is also not a permutation ($$$n=3$$$ but there is $$$4$$$ in the array).

Input

The input consists of multiple test cases. The first line contains a single integer $$$t$$$ ($$$1 \leq t \leq 5 \cdot 10^3$$$) — the number of test cases.

The first line of each test case contains an integer $$$n$$$ ($$$1 \le n \le 10^5$$$).

The second line of each test case contains $$$n$$$ integers $$$c_1,c_2,\ldots,c_n$$$ ($$$1 \leq c_i \leq n$$$).

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$10^5$$$.

Output

For each test case, print "YES" if there is a permutation $$$p$$$ exists that satisfies the array $$$c$$$, and "NO" otherwise.

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

Note

In the first test case, the permutation $$$[1]$$$ satisfies the array $$$c$$$.

In the second test case, the permutation $$$[2,1]$$$ satisfies the array $$$c$$$.

In the fifth test case, the permutation $$$[5, 1, 2, 4, 6, 3]$$$ satisfies the array $$$c$$$. Let's see why this is true.

The zeroth cyclic shift of $$$p$$$ is $$$[5, 1, 2, 4, 6, 3]$$$. Its power is $$$2$$$ since $$$b = [5, 5, 5, 5, 6, 6]$$$ and there are $$$2$$$ distinct elements — $$$5$$$ and $$$6$$$.
The first cyclic shift of $$$p$$$ is $$$[3, 5, 1, 2, 4, 6]$$$. Its power is $$$3$$$ since $$$b=[3,5,5,5,5,6]$$$.
The second cyclic shift of $$$p$$$ is $$$[6, 3, 5, 1, 2, 4]$$$. Its power is $$$1$$$ since $$$b=[6,6,6,6,6,6]$$$.
The third cyclic shift of $$$p$$$ is $$$[4, 6, 3, 5, 1, 2]$$$. Its power is $$$2$$$ since $$$b=[4,6,6,6,6,6]$$$.
The fourth cyclic shift of $$$p$$$ is $$$[2, 4, 6, 3, 5, 1]$$$. Its power is $$$3$$$ since $$$b = [2, 4, 6, 6, 6, 6]$$$.
The fifth cyclic shift of $$$p$$$ is $$$[1, 2, 4, 6, 3, 5]$$$. Its power is $$$4$$$ since $$$b = [1, 2, 4, 6, 6, 6]$$$.

Therefore, $$$c = [2, 3, 1, 2, 3, 4]$$$.

In the third, fourth, and sixth testcases, we can show that there is no permutation that satisfies array $$$c$$$.
