Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
You are given a permutation p of the set {1, 2, ..., N}. Please construct two sequences of positive integers a_1, a_2, ..., a_N and b_1, b_2, ..., b_N satisfying the following conditions:
* 1 \leq a_i, b_i \leq 10^9 for all i
* a_1 < a_2 < ... < a_N
* b_1 > b_2 > ... > b_N
* a_{p_1}+b_{p_1} < a_{p_2}+b_{p_2} < ... < a_{p_N}+b_{p_N}
Constraints
* 2 \leq N \leq 20,000
* p is a permutation of the set {1, 2, ..., N}
Input
The input is given from Standard Input in the following format:
N
p_1 p_2 ... p_N
Output
The output consists of two lines. The first line contains a_1, a_2, ..., a_N seperated by a space. The second line contains b_1, b_2, ..., b_N seperated by a space.
It can be shown that there always exists a solution for any input satisfying the constraints.

Provide a correct Python 3 solution for this coding contest problem.
Write a program that extracts n different numbers from the numbers 0 to 9 and outputs the number of combinations that add up to s. Each n number is from 0 to 9, and the same number cannot be used in one combination. For example, if n is 3 and s is 6, the combination of the three numbers totaling 6 is
1 + 2 + 3 = 6
0 + 1 + 5 = 6
0 + 2 + 4 = 6
There are three ways.
Input
Given multiple datasets. For each dataset, n (1 ≤ n ≤ 9) and s (0 ≤ s ≤ 100) are given on one line, separated by a single space. When both n and s are 0, it is the end of the input (in this case, the program is terminated without processing).
The number of datasets does not exceed 50.

For each dataset, output the number of combinations in which the sum of n integers is s on one line.

Given multiple datasets. For each dataset, n (1 ≤ n ≤ 9) and s (0 ≤ s ≤ 100) are given on one line, separated by a single space. When both n and s are 0, it is the end of the input (in this case, the program is terminated without processing).
The number of datasets does not exceed 50.
Output
For each dataset, output the number of combinations in which the sum of n integers is s on one line.

Input
3 6
3 1
0 0
Output
