Examples

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.
