Day 24 – Two Pointer Technique | LeetCode 125: Valid Palindrome | Tamil #leetcode#coding#viralshorts

Day 24 of my 365 Days LeetCode Challenge 🚀
Today’s problem was 125. Valid Palindrome, solved using the Two Pointer approach.
Instead of creating extra strings, I used: • Left and right pointers
• Skipped non-alphanumeric characters
• Compared characters case-insensitively
This makes the solution: ✅ Time Complexity: O(n)
✅ Space Complexity: O(1)
A simple yet powerful problem to strengthen string manipulation + two pointer logic. Great practice for writing clean and optimized code!
Consistency = Motivation. One problem a day 💯
