Provide a correct Python 3 solution for this coding contest problem. Write a program which reads an integer n and identifies the number of combinations of a, b, c and d (0 ≤ a, b, c, d ≤ 9) which meet the following equality: a + b + c + d = n For example, for n = 35, we have 4 different combinations of (a, b, c, d): (8, 9, 9, 9), (9, 8, 9, 9), (9, 9, 8, 9), and (9, 9, 9, 8). Input The input consists of several datasets. Each dataset consists of n (1 ≤ n ≤ 50) in a line. The number of datasets is less than or equal to 50. Output Print the number of combination in a line.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. A positive integer x is called a power of two if it can be represented as x = 2^y, where y is a non-negative integer. So, the powers of two are 1, 2, 4, 8, 16, .... You are given two positive integers n and k. Your task is to represent n as the sum of exactly k powers of two. Input The only line of the input contains two integers n and k (1 ≤ n ≤ 10^9, 1 ≤ k ≤ 2 ⋅ 10^5). Output If it is impossible to represent n as the sum of k powers of two, print NO. Otherwise, print YES, and then print k positive integers b_1, b_2, ..., b_k such that each of b_i is a power of two, and ∑ _{i = 1}^{k} b_i = n. If there are multiple answers, you may print any of them.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. You have a bag of size n. Also you have m boxes. The size of i-th box is a_i, where each a_i is an integer non-negative power of two. You can divide boxes into two parts of equal size. Your goal is to fill the bag completely. For example, if n = 10 and a = [1, 1, 32] then you have to divide the box of size 32 into two parts of size 16, and then divide the box of size 16. So you can fill the bag with boxes of size 1, 1 and 8. Calculate the minimum number of divisions required to fill the bag of size n. Input The first line contains one integer t (1 ≤ t ≤ 1000) — the number of test cases. The first line of each test case contains two integers n and m (1 ≤ n ≤ 10^{18}, 1 ≤ m ≤ 10^5) — the size of bag and the number of boxes, respectively. The second line of each test case contains m integers a_1, a_2, ... , a_m (1 ≤ a_i ≤ 10^9) — the sizes of boxes. It is guaranteed that each a_i is a power of two. It is also guaranteed that sum of all m over all test cases does not exceed 10^5. Output For each test case print one integer — the minimum number of divisions required to fill the bag of size n (or -1, if it is impossible).

You wrote down all integers from 0 to 10^n - 1, padding them with leading zeroes so their lengths are exactly n. For example, if n = 3 then you wrote out 000, 001, ..., 998, 999. A block in an integer x is a consecutive segment of equal digits that cannot be extended to the left or to the right.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. You are given an integer n (n > 1). Your task is to find a sequence of integers a_1, a_2, …, a_k such that: * each a_i is strictly greater than 1; * a_1 ⋅ a_2 ⋅ … ⋅ a_k = n (i. e. the product of this sequence is n); * a_{i + 1} is divisible by a_i for each i from 1 to k-1; * k is the maximum possible (i. e. the length of this sequence is the maximum possible). If there are several such sequences, any of them is acceptable. It can be proven that at least one valid sequence always exists for any integer n > 1. You have to answer t independent test cases. Input The first line of the input contains one integer t (1 ≤ t ≤ 5000) — the number of test cases. Then t test cases follow. The only line of the test case contains one integer n (2 ≤ n ≤ 10^{10}). It is guaranteed that the sum of n does not exceed 10^{10} (∑ n ≤ 10^{10}). Output For each test case, print the answer: in the first line, print one positive integer k — the maximum possible length of a. In the second line, print k integers a_1, a_2, …, a_k — the sequence of length k satisfying the conditions from the problem statement. If there are several answers, you can print any. It can be proven that at least one valid sequence always exists for any integer n > 1.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. You are given a sequence of positive integers x1, x2, ..., xn and two non-negative integers a and b. Your task is to transform a into b. To do that, you can perform the following moves: * subtract 1 from the current a; * subtract a mod xi (1 ≤ i ≤ n) from the current a. Operation a mod xi means taking the remainder after division of number a by number xi. Now you want to know the minimum number of moves needed to transform a into b. Input The first line contains a single integer n (1 ≤ n ≤ 105). The second line contains n space-separated integers x1, x2, ..., xn (2 ≤ xi ≤ 109).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Given is an integer S. Find a combination of six integers X_1,Y_1,X_2,Y_2,X_3, and Y_3 that satisfies all of the following conditions: * 0 \leq X_1,Y_1,X_2,Y_2,X_3,Y_3 \leq 10^9 * The area of the triangle in a two-dimensional plane whose vertices are (X_1,Y_1),(X_2,Y_2), and (X_3,Y_3) is S/2. We can prove that there always exist six integers that satisfy the conditions under the constraints of this problem. Constraints * 1 \leq S \leq 10^{18} * All values in input are integers.
