You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in c++17.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:
```cpp
<your code here>
```

# Problem
Somewhere in a parallel Middle-earth, when Saruman caught Frodo, he only found $$$n$$$ rings. And the $$$i$$$-th ring was either gold or silver. For convenience Saruman wrote down a binary string $$$s$$$ of $$$n$$$ characters, where the $$$i$$$-th character was 0 if the $$$i$$$-th ring was gold, and 1 if it was silver.

Saruman has a magic function $$$f$$$, which takes a binary string and returns a number obtained by converting the string into a binary number and then converting the binary number into a decimal number. For example, $$$f(001010) = 10, f(111) = 7, f(11011101) = 221$$$.

Saruman, however, thinks that the order of the rings plays some important role. He wants to find $$$2$$$ pairs of integers $$$(l_1, r_1), (l_2, r_2)$$$, such that:

- $$$1 \le l_1 \le n$$$, $$$1 \le r_1 \le n$$$, $$$r_1-l_1+1\ge \lfloor \frac{n}{2} \rfloor$$$
- $$$1 \le l_2 \le n$$$, $$$1 \le r_2 \le n$$$, $$$r_2-l_2+1\ge \lfloor \frac{n}{2} \rfloor$$$
- Pairs $$$(l_1, r_1)$$$ and $$$(l_2, r_2)$$$ are distinct. That is, at least one of $$$l_1 \neq l_2$$$ and $$$r_1 \neq r_2$$$ must hold.
- Let $$$t$$$ be the substring $$$s[l_1:r_1]$$$ of $$$s$$$, and $$$w$$$ be the substring $$$s[l_2:r_2]$$$ of $$$s$$$. Then there exists non-negative integer $$$k$$$, such that $$$f(t) = f(w) \cdot k$$$.

Here substring $$$s[l:r]$$$ denotes $$$s_ls_{l+1}\ldots s_{r-1}s_r$$$, and $$$\lfloor x \rfloor$$$ denotes rounding the number down to the nearest integer.

Help Saruman solve this problem! It is guaranteed that under the constraints of the problem at least one solution exists.

## Input Format
Each test contains multiple test cases.

The first line contains one positive integer $$$t$$$ ($$$1 \le t \le 10^3$$$), denoting the number of test cases. Description of the test cases follows.

The first line of each test case contains one positive integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10^4$$$) — length of the string.

The second line of each test case contains a non-empty binary string of length $$$n$$$.

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

## Output Format
For every test case print four integers $$$l_1$$$, $$$r_1$$$, $$$l_2$$$, $$$r_2$$$, which denote the beginning of the first substring, the end of the first substring, the beginning of the second substring, and the end of the second substring, respectively.

If there are multiple solutions, print any.

## Examples
```input
7
6
101111
9
111000111
8
10000000
5
11011
6
001111
3
101
30
100000000000000100000000000000
```
```output
3 6 1 3
1 9 4 9
5 8 1 4
1 5 3 5
1 6 2 4
1 2 2 3
1 15 16 30
```

## Note
In the first testcase $$$f(t) = f(1111) = 15$$$, $$$f(w) = f(101) = 5$$$.

In the second testcase $$$f(t) = f(111000111) = 455$$$, $$$f(w) = f(000111) = 7$$$.

In the third testcase $$$f(t) = f(0000) = 0$$$, $$$f(w) = f(1000) = 8$$$.

In the fourth testcase $$$f(t) = f(11011) = 27$$$, $$$f(w) = f(011) = 3$$$.

In the fifth testcase $$$f(t) = f(001111) = 15$$$, $$$f(w) = f(011) = 3$$$.

Now solve the problem and return the code.
