#include<bits/stdc++.h>
using namespace std;
mt19937 g(114514);
int main(){
int s,x;scanf("%d%d",&s,&x);
if(__gcd(x,s)==1)return printf("1\n%d",s),0;
bool flag=false;
if(s&1&&~x&1)flag=true,s--;
int y,z;
do y=g()%1000000000+1,z=s-y;
while(__gcd(x,y)!=1||__gcd(x,abs(z))!=1);
if(flag)printf("3\n1 %d %d",y,z);
else printf("2\n%d %d",y,z);
return 0;
}
这程序好像有点Bug，我给组数据试试？
