Special Integers

An Integer $x$ is called special in this case when, for every positive integer $y$ such that $y \gt x$, $\frac{x}{f(x)} \leq \frac{y}{f(y)}$ holds. Where, $f(d)$ denotes the sum of the digits in the decimal representation on $d$. Given a range $[A, B]$ find $(B - A + 1)$ special numbers, specifically meaning find them starting from the $A$th smallest special number to $B$ th smallest special num
