You are given a string s.

\n\n

Your task is to remove all digits by doing this operation repeatedly:

\n\n\n\n

Return the resulting string after removing all digits.

\n\n

 

\n

Example 1:

\n\n
\n

Input: s = "abc"

\n\n

Output: "abc"

\n\n

Explanation:

\n\n

There is no digit in the string.

\n
\n\n

Example 2:

\n\n
\n

Input: s = "cb34"

\n\n

Output: ""

\n\n

Explanation:

\n\n

First, we apply the operation on s[2], and s becomes "c4".

\n\n

Then we apply the operation on s[1], and s becomes "".
