Palindrome Linked List
Detailed guide and Python implementation for the 'Palindrome Linked List' problem.
Problem Statement
Write a function is_palindrome_list(arr) that represents a singly linked list as a Python list arr, and returns True if it is a palindrome, and False otherwise.
- •0 <= len(arr) <= 10^5
- •0 <= arr[i] <= 9
Examples
arr = [1, 2, 2, 1]
True
The list reads the same forward and backward.
arr = [1, 2, 3]
False
The list reads [1, 2, 3] forward but [3, 2, 1] backward, which is not equal.
