Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

standard inputoutput

standard outputYou had a sequence $$$a_1, a_2, \ldots, a_n$$$ consisting of integers from $$$1$$$ to $$$n$$$, not necessarily distinct. For some unknown reason, you decided to calculate the following characteristic of the sequence:

- Let $$$r_i$$$ ($$$1 \le i \le n$$$) be the smallest $$$j \ge i$$$ such that on the subsegment $$$a_i, a_{i+1}, \ldots, a_j$$$ all distinct numbers from the sequence $$$a$$$ appear. More formally, for any $$$k \in [1, n]$$$, there exists $$$l \in [i, j]$$$ such that $$$a_k = a_l$$$. If such $$$j$$$ does not exist, $$$r_i$$$ is considered to be equal to $$$n+1$$$.
- The characteristic of the sequence $$$a$$$ is defined as the sequence $$$r_1, r_2, \ldots, r_n$$$.

Input

Each test consist of multiple test cases. The first line contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases. The description of test cases follows.

The first line of each test case contains a single integer $$$n$$$ ($$$1 \le n \le 2 \cdot 10^5$$$) — the length of the lost sequence $$$a$$$.

The second line of each test case contains $$$n$$$ integers $$$r_1, r_2, \ldots, r_n$$$ ($$$i \le r_i \le n+1$$$) — the characteristic of the lost sequence $$$a$$$.

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.

Output

For each test case, output the following:

- If there is no sequence $$$a$$$ with the characteristic $$$r$$$, print "No".
- Otherwise, print "Yes" on the first line, and on the second line, print any sequence of integers $$$a_1, a_2, \ldots, a_n$$$ ($$$1 \le a_i \le n$$$) that matches the characteristic $$$r$$$.

Example

Input

532 3 452 3 5 4 61131 3 483 6 6 6 8 9 9 9

Output

Yes 1 2 1 No Yes 1 No Yes 1 3 5 3 5 1 1 3

Note

In the first test case, the sequence $$$a = [1, 2, 1]$$$ is suitable. The integers $$$1$$$ and $$$2$$$ appear on the subsegments $$$[1, 2]$$$ and $$$[2, 3]$$$.

In the second test case, it can be proved that there is no suitable sequence $$$a$$$.
