题目描述

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

  • F(k,n)=0F(k,n)=0 , for integer nn , 1<=n<k ;
  • F(k,k)=1F(k,k)=1 ;
  • F(k,n)=F(k,n1)+F(k,n2)+...+F(k,nk)F(k,n)=F(k,n-1)+F(k,n-2)+...+F(k,n-k) , for integer nn , n>k .

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

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

输入格式

The first line contains two integers ss and kk (1<=s,k<=10^{9}; k>1) .

输出格式

In the first line print an integer mm (m>=2)(m>=2) that shows how many numbers are in the found representation. In the second line print mm distinct integers a1,a2,...,ama_{1},a_{2},...,a_{m} . Each printed integer should be a kk -bonacci number. The sum of printed integers must equal ss .

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