Valid Sudoku - Leetcode 36 | 3 Optimal Approaches

🧩 PROBLEM DESCRIPTION Determine if a 9 x 9 Sudoku board is valid. Only the filled cells need to be validated **according to the following rules**: 1. Each row must contain the digits 1-9 without repetition. 2. Each column must contain the digits 1-9 without repetition. 3. Each of the nine 3 x 3 sub-boxes of the grid must contain the digits 1-9 without repetition. *Note:* A Sudoku board (partially filled) could be valid but is not necessarily solvable. Only the filled cells need to be validated according to the mentioned rules. The Sudoku board could be partially filled, where empty cells are filled with the character '.'. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🔗 LINKS ⭐Problem: https://leetcode.com/problems/valid-s... 💻Code: https://k5kc.com/cs/problems/valid-su... ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📂 RELATED PLAYLISTS To Explore 📃 Array Datastructure:    • Array Datastructure   🔑 Hashmap Datastructure:    • Hashmap Datastructure   📐 Matrix Datastructure:    • Matrix Datastructure   🟡 Medium Coding Problem:    • Medium Coding Problem   ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🔔 SUPPORT AND SUBSCRIBE Don’t forget to *like**, **subscribe**, and **comment* for more problem-solving content! 🚀 🎯 _Follow me for updates_: GitHub: https://github.com/k5kc Twitter: https://x.com/k5kc_ Instagram:   / _k5kc_   LinkedIn:   / k5kc
