akhauriyash/Code-Regression huggingface dataset:
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.

There are $X$ people participating in a quiz competition and their IDs have been numbered from $1$ to $X$ (both inclusive). Beth needs to form a team among these $X$ participants. She has been given an integer $Y$. She can choose participants whose ID numbers are divisible by $Y$. 
Now that the team is formed, Beth wants to know the strength of her team. The strength of a team is the sum of all the last digits of the team members’ ID numbers.
Can you help Beth in finding the strength of her team?

-----Input:-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. $T$ lines follow 
- The first line of each test case contains $X$ and $Y$. 

-----Output:-----
- For each test case print the strength of Beth's team

-----Constraints-----
- $1 \leq T \leq 1000$
- $1 \leq X,Y \leq 10^{20}$

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

10 3

15 5

-----Sample Output:-----
18 

10

-----EXPLANATION:-----
- Example case 1: ID numbers divisible by 3 are 3,6,9 and the sum of the last digits are 3+6+9=18

Iroha has a sequence of N strings S_1, S_2, ..., S_N. The length of each string is L.
She will concatenate all of the strings in some order, to produce a long string.
Among all strings that she can produce in this way, find the lexicographically smallest one.
Here, a string s=s_1s_2s_3...s_n is lexicographically smaller than another string t=t_1t_2t_3...t_m if and only if one of the following holds:

 - There exists an index i(1≦i≦min(n,m)), such that s_j = t_j for all indices j(1≦j<i), and s_i<t_i.
 - s_i = t_i for all integers i(1≦i≦min(n,m)), and n<m.

-----Constraints-----
 - 1 ≦ N, L ≦ 100
 - For each i, the length of S_i equals L.
 - For each i, S_i consists of lowercase letters.

-----Input-----
The input is given from Standard Input in the following format:
N L
S_1
S_2
:
S_N

-----Output-----
Print the lexicographically smallest string that Iroha can produce.

-----Sample Input-----
3 3
dxx
axx
cxx

-----Sample Output-----
axxcxxdxx

The following order should be used: axx, cxx, dxx.

Chef has a sequence $A_1, A_2, \ldots, A_N$. This sequence has exactly $2^N$ subsequences. Chef considers a subsequence of $A$ interesting if its size is exactly $K$ and the sum of all its elements is minimum possible, i.e. there is no subsequence with size $K$ which has a smaller sum.
Help Chef find the number of interesting subsequences of the sequence $A$.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of each test case contains two space-separated integers $N$ and $K$.
- The second line contains $N$ space-separated integers $A_1, A_2, \ldots, A_N$.

-----Output-----
For each test case, print a single line containing one integer ― the number of interesting subsequences.

-----Constraints-----
- $1 \le T \le 10$
- $1 \le K \le N \le 50$
- $1 \le A_i \le 100$ for each valid $i$

-----Subtasks-----
Subtask #1 (30 points): $1 \le N \le 20$
Subtask #2 (70 points): original constraints

-----Example Input-----
1
4 2
1 2 3 4

-----Example Output-----
1

-----Explanation-----
Example case 1: There are six subsequences with length $2$: $(1, 2)$, $(1, 3)$, $(1, 4)$, $(2, 3)$, $(2, 4)$ and $(3, 4)$. The minimum sum is $3$ and the only subsequence with this sum is $(1, 2)$.

The students of Codechef Middle School are visiting an amusement park. The children want to go on a ride, however, there is a minimum height requirement of $X$ cm. Determine if the children are eligible to go on the ride. 
Print "Yes" if they are eligible, "No" otherwise.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, two integers $H$ which is a child's height in cm and $X$ which is the minimum permissible height. 

-----Output:-----
For each testcase, output in a single line $"Yes"$ or $"No"$. You cannot give your answer as "YeS", "YES", "yes" or any other variation.

-----Constraints-----
- $1 \leq T \leq 10^4$
- $50 \leq H \leq 200$
- $50 \leq X \leq 200$

-----Sample Input:-----
2
120 100
90 100

-----Sample Output:-----
Yes
No

-----EXPLANATION:-----
The first child has height more than minimum permissible height, so he can go on the ride while the other person cannot!

Richik$Richik$ has just completed his engineering and has got a job in one of the firms at Sabrina$Sabrina$ which is ranked among the top seven islands in the world in terms of the pay scale. 
Since Richik$Richik$ has to travel a lot to reach the firm, the owner assigns him a number X$X$, and asks him to come to work only on the day which is a multiple of X$X$. Richik joins the firm on 1-st day but starts working from X-th day. Richik$Richik$ is paid exactly the same amount in Dollars as the day number. For example, if Richik$Richik$ has been assigned X=3$X = 3$, then he will be paid 3$3$ dollars and 6$6$ dollars on the 3rd$3rd$ and 6th$6th$ day on which he comes for work. 
On N−th$N-th$ day, the owner calls up Richik$Richik$ and asks him not to come to his firm anymore. Hence Richik$Richik$ demands his salary of all his working days together. Since it will take a lot of time to add, Richik$Richik$ asks help from people around him, let's see if you can help him out. 

-----Input:-----
- First line will contain T$T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, two integers X,N$X, N$. 

-----Output:-----
For each testcase, output in a single line which is the salary which Richik$Richik$ demands. 

-----Constraints-----
- 1≤T≤1000$1 \leq T \leq 1000$
- 1≤X<=N≤107$1 \leq X<=N \leq 10^7$
