    3174 - Clear Digits.

    Easy

    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.

    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.
