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 outputFor an array $$$a$$$ of integers let's denote its maximal element as $$$\max(a)$$$, and minimal as $$$\min(a)$$$. We will call an array $$$a$$$ of $$$k$$$ integers interesting if $$$\max(a) - \min(a) \ge k$$$. For example, array $$$[1, 3, 4, 3]$$$ isn't interesting as $$$\max(a) - \min(a) = 4 - 1 = 3 < 4$$$ while array $$$[7, 3, 0, 4, 3]$$$ is as $$$\max(a) - \min(a) = 7 - 0 = 7 \ge 5$$$.

You are given an array $$$a$$$ of $$$n$$$ integers. Find some interesting nonempty subarray of $$$a$$$, or tell that it doesn't exist.

An array $$$b$$$ is a subarray of an array $$$a$$$ if $$$b$$$ can be obtained from $$$a$$$ by deletion of several (possibly, zero or all) elements from the beginning and several (possibly, zero or all) elements from the end. In particular, an array is a subarray of itself.

Input

The first line contains integer number $$$t$$$ ($$$1 \le t \le 10\,000$$$). Then $$$t$$$ test cases follow.

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

The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, \dots, a_n$$$ ($$$0\le a_i \le 10^9$$$) — the elements of the array.

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 "NO" in a separate line if there is no interesting nonempty subarray in $$$a$$$.

Otherwise, output "YES" in a separate line. In the next line, output two integers $$$l$$$ and $$$r$$$ ($$$1\le l \le r \le n$$$) — bounds of the chosen subarray. If there are multiple answers, print any.

You can print each letter in any case (upper or lower).

Example

Input

3 5 1 2 3 4 5 4 2 0 1 9 2 2019 2020

Output

NO YES 1 4 NO

Note

In the second test case of the example, one of the interesting subarrays is $$$a = [2, 0, 1, 9]$$$: $$$\max(a) - \min(a) = 9 - 0 = 9 \ge 4$$$.
