You are given a special jigsaw puzzle consisting of $n\cdot m$ identical pieces. Every piece has three tabs and one blank, as pictured below. $\{3$ 

The jigsaw puzzle is considered solved if the following conditions hold:  The pieces are arranged into a grid with $n$ rows and $m$ columns.  For any two pieces that share an edge in the grid, a tab of one piece fits perfectly into a blank of the other piece. 

Through rotation and translation of the pieces, determine if it is possible to solve the jigsaw puzzle.


-----Input-----

The test consists of multiple test cases. The first line contains a single integer $t$ ($1\le t\le 1000$) — the number of test cases. Next $t$ lines contain descriptions of test cases.

Each test case contains two integers $n$ and $m$ ($1 \le n,m \le 10^5$).


-----Output-----

For each test case output a single line containing "YES" if it is possible to solve the jigsaw puzzle, or "NO" otherwise. You can print each letter in any case (upper or lower).


-----Example-----
Input
3
1 3
100000 100000
2 2

Output
YES
NO
YES



-----Note-----

For the first test case, this is an example solution:  [Image] 

For the second test case, we can show that no solution exists.

For the third test case, this is an example solution: $\left\{\begin{array}{l}{3} \\{3} \end{array} \right\}$

-----General Statement:-----
Read a number in scientific notation and output its equivalent decimal value.

-----Input:-----
All data is on a single line. The first integer indicates how many pairs of numbers follow. The first of each pair is A, the base number, and the second is E, the power of 10.

-----Output:-----
Round each answer to 2 decimal places. Trailing zeros to the right of the decimal point are required. A leading zero to the left of the decimal point is not required.
The output is to be formatted exactly like that for the sample output given below.

-----Assumptions:-----
E is in the range –10 .. 10. A is 1 or larger but less than 10.
Discussion: 
If A = 3.926 and E = 4, the number represented is 3.926 X 104 or 39260, which is 39260.00 when rounded to 2 decimal places.

-----Sample Input:-----
4 4.296 3 3.8 -2 1.8 2 2.8678 1

-----Sample Output:-----
4296.00
0.04
180.00

Eighth-grader Vova is on duty today in the class. After classes, he went into the office to wash the board, and found on it the number n. He asked what is this number and the teacher of mathematics Inna Petrovna answered Vova that n is the answer to the arithmetic task for first-graders. In the textbook, a certain positive integer x was given. The task was to add x to the sum of the digits of the number x written in decimal numeral system.

Since the number n on the board was small, Vova quickly guessed which x could be in the textbook. Now he wants to get a program which will search for arbitrary values of the number n for all suitable values of x or determine that such x does not exist. Write such a program for Vova.


-----Input-----

The first line contains integer n (1 ≤ n ≤ 10^9).


-----Output-----

In the first line print one integer k — number of different values of x satisfying the condition. 

In next k lines print these values in ascending order.


-----Examples-----
Input
21

Output
1
15

Input
20

Output
0



-----Note-----

In the first test case x = 15 there is only one variant: 15 + 1 + 5 = 21.

In the second test case there are no such x.

(s contains only 'R', 'B', 'G', 'O', and 'V' characters denoting red, blue, green, orange, and violet respectively)

-----Output:-----
For each test case, print single line containing one integer - The minimum number of pens that need to be taken out.

-----Constraints-----
- $1 \leq T \leq 100$
- $1 \leq n \leq 1000$

-----Sample Input:-----

-----EXPLANATION:-----
In first test case, two blue pens are neighboring each other, if we take out any one of them then the string will be RBRG in which each pen has different neighbors.
In second test case, no pen needs to be taken out as each pen has different neighbors.

There are $n$ programmers that you want to split into several non-empty teams. The skill of the $i$-th programmer is $a_i$. You want to assemble the maximum number of teams from them. There is a restriction for each team: the number of programmers in the team multiplied by the minimum skill among all programmers in the team must be at least $x$.

Each programmer should belong to at most one team. Some programmers may be left without a team.

Calculate the maximum number of teams that you can assemble.


-----Input-----

The first line contains the integer $t$ ($1 \le t \le 1000$) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ($1 \le n \le 10^5; 1 \le x \le 10^9$) — the number of programmers and the restriction of team skill respectively.

The second line of each test case contains $n$ integers $a_1, a_2, \dots , a_n$ ($1 \le a_i \le 10^9$), where $a_i$ is the skill of the $i$-th programmer.

The sum of $n$ over all inputs does not exceed $10^5$.


-----Output-----

For each test case print one integer — the maximum number of teams that you can assemble.

Consider a sequence [a_1, a_2, ... , a_{n}]. Define its prefix product sequence $[ a_{1} \operatorname{mod} n,(a_{1} a_{2}) \operatorname{mod} n, \cdots,(a_{1} a_{2} \cdots a_{n}) \operatorname{mod} n ]$.

Now given n, find a permutation of [1, 2, ..., n], such that its prefix product sequence is a permutation of [0, 1, ..., n - 1].


-----Input-----

The only input line contains an integer n (1 ≤ n ≤ 10^5).


-----Output-----

In the first output line, print "YES" if such sequence exists, or print "NO" if no such sequence exists.

If any solution exists, you should output n more lines. i-th line contains only an integer a_{i}. The elements of the sequence should be different positive integers no larger than n.

If there are multiple solutions, you are allowed to print any of them.


-----Examples-----

Vishal Wants to buy 2 gifts for his best friend whose name is Annabelle(her age is 20), So they both went for shopping in a store. But Annabelle gave, Vishal a condition that she will accept this gifts only when the total price of the gifts is the same as her age times 100.
The store contains, a list of items whose prices are also displayed, Now Vishal is asking for your help to buy gifts, as he wants to impress Annabelle this time.
Note: Vishal cannot buy the same item more than once.

-----Input:-----
- The first line of the input contains a single integer $T$. $T$ denoting the number of test cases. The description of $T$ test cases is as follows.
- The next line of the input contains a single integer $N$. $N$ denotes the total number of items in store.
- The next line of the input contains $N$ space-separated integers $A1, A2, A3...An$ where $ith$ number denotes the price of $ith$ element.

-----Output:-----
- For each test-case print "Accepted"(without quotes) if the gifts are accepted by Annabelle, else print "Rejected"(without quotes)

-----Constraints:-----
- $1 \leq T \leq 10^3$

Hooray! Polycarp turned $n$ years old! The Technocup Team sincerely congratulates Polycarp!

Polycarp celebrated all of his $n$ birthdays: from the $1$-th to the $n$-th. At the moment, he is wondering: how many times he turned beautiful number of years?

According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: $1$, $77$, $777$, $44$ and $999999$. The following numbers are not beautiful: $12$, $11110$, $6969$ and $987654321$.

Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10).

Help Polycarpus to find the number of numbers from $1$ to $n$ (inclusive) that are beautiful.


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case consists of one line, which contains a positive integer $n$ ($1 \le n \le 10^9$) — how many years Polycarp has turned.


-----Output-----

Print $t$ integers — the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between $1$ and $n$, inclusive.


-----Example-----
Input
6
18
1
9
100500
33
1000000000

Output
10
1
9
45
12
81



-----Note-----

In the first test case of the example beautiful years are $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$ and $11$.

Eighth-grader Vova is on duty today in the class. After classes, he went into the office to wash the board, and found on it the number n. He asked what is this number and the teacher of mathematics Inna Petrovna answered Vova that n is the answer to the arithmetic task for first-graders. In the textbook, a certain positive integer x was given. The task was to add x to the sum of the digits of the number x written in decimal numeral system.

Since the number n on the board was small, Vova quickly guessed which x could be in the textbook. Now he wants to get a program which will search for arbitrary values of the number n for all suitable values of x or determine that such x does not exist. Write such a program for Vova.


-----Input-----

The first line contains integer n (1 ≤ n ≤ 10^9).


-----Output-----

In the first line print one integer k — number of different values of x satisfying the condition. 

In next k lines print these values in ascending order.


-----Examples-----
Input

You are given a special jigsaw puzzle consisting of $n\cdot m$ identical pieces. Every piece has three tabs and one blank, as pictured below. $\{3$ 

The jigsaw puzzle is considered solved if the following conditions hold:  The pieces are arranged into a grid with $n$ rows and $m$ columns.  For any two pieces that share an edge in the grid, a tab of one piece fits perfectly into a blank of the other piece. 

Through rotation and translation of the pieces, determine if it is possible to solve the jigsaw puzzle.


-----Input-----

The test consists of multiple test cases. The first line contains a single integer $t$ ($1\le t\le 1000$) — the number of test cases. Next $t$ lines contain descriptions of test cases.

Each test case contains two integers $n$ and $m$ ($1 \le n,m \le 10^5$).


-----Output-----

For each test case output a single line containing "YES" if it is possible to solve the jigsaw puzzle, or "NO" otherwise. You can print each letter in any case (upper or lower).


-----Example-----
Input
3
1 3
100000 100000
2 2

Output
YES
NO
YES



-----Note-----

For the first test case, this is an example solution:  [Image] 

For the second test case, we can show that no solution exists.

For the third test case, this is an example solution: $\left\{\begin{array}{l}{3} \\{3} \end{array} \right\}$
