In this video, I solve LeetCode 234: Palindrome Linked List using a very simple and beginner-friendly approach:
👉 Convert the linked list into a vector
👉 Check if the vector is a palindrome using recursion
This solution is extremely easy to understand and perfect for beginners who want to first learn the logic clearly before moving to advanced pointer techniques.
🧠 Approach Used in This Video
✔ Traverse the linked list and store values in a vector
✔ Use a recursive function palin(i, j) to check if the array is a palindrome
✔ Compare elements from both ends
✔ Time Complexity: O(n)
✔ Space Complexity: O(n) (because of vector + recursion stack)
This approach is ideal for clarity and understanding the palindrome concept step-by-step.
📘 Code Breakdown
We use:
A helper function palin() for recursion
Base condition when indexes cross
Return false immediately if a mismatch is found
Clean and readable implementation
This method is different from the usual fast & slow pointer technique, but it is one of the simplest ways to check a palindrome.
