Teaching Kids Programming: Videos on Data Structures and Algorithms 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, and s becomes “c4”. Then we apply the operation on s, and s becomes “”. Constraints: 1 <= s.length <= 100 Continue Reading »
