Valid Palindrome - LeetCode 125 | Day 6 of My Coding Journey

🎯 Day 6 of My LeetCode Journey | Valid Palindrome Problem In this video, I solve LeetCode Problem #125 - Valid Palindrome, an easy-level problem that introduces the powerful Two Pointer technique! This is a fundamental problem that appears frequently in coding interviews. 🔗 Problem Link: https://leetcode.com/problems/valid-p... 📌 PROBLEM DESCRIPTION: A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Given a string s, return true if it is a palindrome, or false otherwise. Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome. Example 3: Input: s = " " Output: true Explanation: Empty string after removing non-alphanumeric characters is a palindrome. 💡 KEY CONCEPTS COVERED: ✅ Two Pointer Technique ✅ String Manipulation ✅ Character Validation (Alphanumeric) ✅ Case Insensitive Comparison ✅ In-place Algorithm 📊 COMPLEXITY: • Time Complexity: O(n) • Space Complexity: O(1) 🎓 DIFFICULTY: Easy 🏷️ TOPICS: Two Pointers, String 🔔 SUBSCRIBE for daily LeetCode solutions and coding challenges! 👍 LIKE if you found this helpful! 💬 COMMENT your approach or questions below! --- 📚 MY LEETCODE JOURNEY PLAYLIST:    • Leetcode   🤝 CONNECT WITH ME: • GitHub: https://github.com/ashwinikemshetty • LinkedIn:   / ashwinikemshetty   --- #LeetCode #CodingInterview #Day6 #ValidPalindrome #Programming #LeetCode125 #TwoPointers #StringManipulation #EasyProblem #CodingChallenge #TechInterview #SoftwareEngineering #AlgorithmExplained #100DaysOfCode
