+2390. Removing Stars From a String(Medium)
+
+You are given a string s, which contains stars *.
+
+In one operation, you can:
+
+Choose a star in s.
+Remove the closest non-star character to its left, as well as remove the star itself.
+Return the string after all stars have been removed.
+
+Note:
+
+The input will be generated such that the operation is always possible.
+It can be shown that the resulting string will always be unique.
+ 
+
+Example 1:
+
+Input: s = "leet**cod*e"
+Output: "lecoe"
+Explanation: Performing the removals from left to right:
+- The closest character to the 1st star is 't' in "leet**cod*e". s becomes "lee*cod*e".
+- The closest character to the 2nd star is 'e' in "lee*cod*e". s becomes "lecod*e".
+- The closest character to the 3rd star is 'd' in "lecod*e". s becomes "lecoe".
+There are no more stars, so we return "lecoe".
+Example 2:
+
+Input: s = "erase*****"
+Output: ""
+Explanation: The entire string is removed, so we return an empty string.
+ 
+
+Constraints:
+
+1 <= s.length <= 105
+s consists of lowercase English letters and stars *.
+The operation above can be performed on s.
