Remove K Digits: coding question

Available question text

Given a numeric string, remove exactly k digits (preserving the remaining order) to form the smallest possible integer, trimming leading zeros and returning "0" if nothing remains. This is a greedy/monotonic-stack style problem where you remove digits that create larger prefixes to minimize the result under the constraint k ≤ n.
