LeetCode 3170 | Lexicographically Minimum String After Removing Stars | Medium | Weekly Contest 400

LeetCode Weekly Contest 400 Problem: https://leetcode.com/problems/lexicog... Hello friends! In this video, we'll discuss an interesting problem involving string manipulation. Problem Statement: You are given a string s that may contain any number of '*' characters. Our task is to remove all '*' characters by performing the following operations: Delete the leftmost '*' and the smallest non-'*' character to its left. If there are multiple smallest characters, we can delete any of them. Continue this process until all '*' characters are removed. Our goal is to return the lexicographically smallest resulting string after all '*' characters are removed. Approaches Discussed: Brute Force (Approach 1): We'll start with a straightforward approach to solve the problem step by step. Optimized Brute Force (Approach 2): Next, we'll enhance the brute force approach to improve efficiency. Optimized Solution (Approach 3): Finally, we'll discuss a linear time solution for this problem. Even though Approaches 1 and 2 might throw a Time Limit Exceeded Error in practical scenarios, it's crucial to understand and approach problems from a brute force perspective initially, especially during interviews. By the end of this video, you'll have a comprehensive understanding of how to approach and solve this problem effectively.
