Lexicographically Smallest String After Deleting Duplicate Characters 🔥 LeetCode 3816 | Optimal

In this video, we solve LeetCode 3816 – Lexicographically Smallest String After Deleting Duplicate Characters, the hard problem (Q4) from Weekly Contest 485. Code: https://leetcode.com/problems/lexicog... Upsolve Leetcode Contest:    • Leetcode Contests   Greedy & Heaps:    • Greedy & Heaps   Two pointers:    • Two pointers   Sliding Window:    • Sliding Window   Maths & Geometry:    • Maths & Geometry   Stack:    • Stack   Set & Map:    • Set & Map   Bit manipulation:    • Bit Manipulation   Backtracking:    • Backtracking   Linked List:    • Linked List   Binary Search:    • Binary Search   Graph:    • Graph   Dynamic Progamming:    • Dynamic Programming   You are given a string consisting of lowercase English letters, and you can repeatedly choose any character that appears at least twice and delete one occurrence. The goal is to form the lexicographically smallest possible string. In this solution, we cover: Frequency counting of characters Greedy strategy to build the smallest lexicographical string Deciding when to remove or keep characters Using StringBuilder efficiently Handling edge cases correctly Clean and optimized Java implementation This problem is a classic example of greedy string manipulation, a very important pattern for LeetCode hard problems and coding interviews.
