Challenge 7: Find Middle Node of Linked List

Problem statement

You have to implement the FindMid() function, which is a member function of a LinkedList, and it should return the value of the middle node. If the length of the list is even, the middle value will occur at $\frac{length}{2}$. For a list of odd length, the middle value will be $\frac{length}{2}+1$.

Input

A linked list is the input.

Output

Middle element of the linked list is the output.

Sample input

LinkedList = 7->14->10->21->null

Sample output

14
