#include <bits/stdc++.h>
using namespace std;
int n,m;
int ans=0;
void dfs(int a,int b,int op)
{// cout<<a<<" "<<b<<endl;
if(a<=n && b<=m) ans++;
if(a>max(n,m) || b>max(n,m)) return;
if(!op)dfs(b,a,1);
dfs(a+2*b,b,0);//注意，这里不能用if(a+2*b<=n)判断，因为有些大于n的a可以经过交换操作变得合法。
}
int main()
{
freopen("number.in","r",stdin);
freopen("number.out","w",stdout);
scanf("%d%d",&n,&m);
dfs(2,1,0);
printf("%d",ans);
