Prof. Pang has an extraordinary vision. He can see the pixels on a 4K monitor. To test Prof. Pang's vision, Prof. Shou will show Prof. Pang several pixels and let Prof. Pang guess a straight line that contains these pixels. Given $k$ pixels with coordinates $(i, y_i)$ ($0\le i<k$), Prof. Pang must find nonnegative integers $a, b$ and $c$ (which represent the line $y=\frac{ax+b}{c}$) such that $y_i=\lfloor \frac{ai+b}{c} \rfloor$ for all $0\le i<k$.
Prof. Shou will ask Prof. Pang multiple questions. They are given as follows: Prof. Shou has a fixed array $x_1,\ldots, x_n$. For each question, Prof. Shou chooses a range in the array, $x_l,\ldots, x_r$. Then he defines $y_i=x_{l+i}$ for $0\le i\le r - l$ and asks Prof. Pang to answer the question for the $r-l+1$ pixels $(0, y_0), \ldots, (r-l, y_{r-l})$.
Please help Prof. Pang answer all the questions. For each question, output the answer with the **minimum** $(c, a, b)$ **in lexical order**.
It is guaranteed that the answer exists when Prof. Pang chooses the whole array $x_1, x_2, \dots, x_n$. So the answer always exists when Prof. Pang chooses an interval of this array.
## Input
The first line contains a single integer $T$ ($1\le T\le 10^5$) denoting the number of test cases.
For each test case, the first line contains an integer $n$ ($1\leq n\leq 10^5$). The second line contains $n$ numbers $x_1, \ldots , x_{n}$ ($0\leq x_i\leq 10^9$).
The next line contains an integer $q$ ($1\le q\le 10^5$) denoting the number of questions.
Each of the following $q$ lines contains two integers $l, r$ ($1\le l\le r\le n$).
It is guaranteed that the sum of $n$ over all test cases will not exceed $10^5$ and that the sum of $q$ over all test cases will not exceed $10^5$.
## Output
In the order of input, output one line with three integers $a, b, c$ denoting the answer for each question.
