Longest Palindrome In A Linked List

easy
1. You are given a linked list with N nodes.
  2. You have to write a function that returns returns an integer denoting
     the length of the longest palindrome list that exist in the given linked list.
  3. For Example:
     Input  : List = 2->3->7->3->2->12->24
     Output : 5
     The longest palindrome list is 2->3->7->3->2
  4. display is a utility function which displays the contents of Linked List,
     feel free to use it for debugging purposes.
  5. main takes input from the users and creates the Linked List. You can use
     display to know its contents.
  6. This is a functional problem. 
  7. You should code only the maxPalindrome function. It takes as input the
     heads of the linked list. It should return the length of the longest
     palindrome in the linked list.
  8. Don't change the code of Node, main and display.

Input Format

First line takes N, the number of elements in the list. Second line takes input N space separated numbers reperesenting elements of the linked list. Input is handled for you.

Output Format

Maximum length of palindrome Output is handled for you.

Constraints

1 <= N <= 1000
