2390. Removing Stars From a String
2390. Removing Stars From a String
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".
