 ## 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.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
-```
+Input: s = "abc"
+
+Output: "abc"
 
-## 题意
-> ...
+Explanation:
 
-## 题解
+There is no digit in the string.
+```
+
+**Example 2:**
 
-### 思路1
-> ...
-Clear Digits
-```go
 ```
+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 "".
+```
