Problem: Numbers k-bonacci (k is integer, k > 1) are a generalization of Fibonacci numbers and are determined as follows:

  * F(k, n) = 0, for integer n, 1 ≤ n < k; 
  * F(k, k) = 1; 
  * F(k, n) = F(k, n - 1) + F(k, n - 2) + ... + F(k, n - k), for integer n, n > k. 



Note that we determine the k-bonacci numbers, F(k, n), only for integer values of n and k.

You've got a number s, represent it as a sum of several (at least two) distinct k-bonacci numbers. 

Input

The first line contains two integers s and k (1 ≤ s, k ≤ 109; k > 1).

Output

In the first line print an integer m (m ≥ 2) that shows how many numbers are in the found representation. In the second line print m distinct integers a1, a2, ..., am. Each printed integer should be a k-bonacci number. The sum of printed integers must equal s.

It is guaranteed that the answer exists. If there are several possible answers, print any of them.

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
int s, k, i, j;
long long f[50];
vector<long long> v;
int main() {
  scanf("%d %d", &s, &k);
  f[0] = 1;
  for (i = 1; f[i - 1] <= s; i++)
    for (j = 1; j <= i && j <= k; j++) f[i] += f[i - j];
  for (i -= 2; i >= 0; i--)
    if (f[i] <= s) v.push_back(f[i]), s -= f[i];
  v.push_back(0);
  printf("%d\n", v.size());
  for (i = v.size() - 1; i > 0; i--) printf("%I64d ", v[i]);
  printf("%I64d\n", v[i]);
  return 0;
