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.
