-// 2390. Removing Stars From a String
-#include "leetcode.h"

-/*
- * given a string 's', which contains stars (*). in one operation
- * you can choose a start in 's', remove the closest non-star
- * character to its left, as well remove the star itself.
- * return string after all stars have been removed. note, the
- * input will be generated such that the operation is always
- * possible, and the resulting string will always be unique
