  "task_description": "You are given a string `s`. Your task is to remove **all** digits by doing this operation repeatedly: Delete the _first_ digit and the **closest** non-digit character to its _left_. Return the resulting string after removing all digits. **Note** that the operation _cannot_ be performed on a digit that does not have any non-digit character to its left. **Example 1:** **Input:** s = \"abc\" **Output:** \"abc\" **Explanation:** There is no digit in the string. **Example 2:** **Input:** s = \"cb34\" **Output:** \"\" **Explanation:** First, we apply the operation on `s[2]`, and `s` becomes `\"c4\"`. Then we apply the operation on `s[1]`, and `s` becomes `\"\"`. **Constraints:** `1 <= s.length <= 100` `s` consists only of lowercase English letters and digits. The input is generated such that it is possible to delete all digits.",
