int n,m,a[10000];
bool BS(int x)
{
  int p,q,i,L;
  p=0;
  q=x-1;
  L=0;
  while (p<=q)
  {
    i=(p+q)/2;
    ++L;
    if (i==n) return (L==m);
    if (n<i) q=i-1; else p=i+1;
  }
  return (L==m)&&(i==n);
}
int main()
{
    freopen("input.txt","r",stdin);
    freopen("output.txt","w",stdout);
    int i,j,k,l,r,e=0,u=0;
    scanf("%d%d",&n,&m);
    for(i=1;i<=10000;i++)
    {
        if (BS(i))
        {
            if (i-e>1)
            {
                a[++u]=e;
                a[++u]=i;
            }
            e=i;
        }
    }
    a[++u]=e;
    printf("%d\n",u/2);
    for(i=1;i<=u/2;i++)
    {
        printf("%d %d\n",a[2*i],a[2*i+1]);
    }
    return 0;
}
