This technical problem deals with singly linked lists, and specifically with checking if a given singly linked list is a palindrome. A palindrome is defined as a word, phrase , or sequence that reads the same backward as forward, and so in this context, a palindrome linked list would be one where the order of the nodes is the same whether you traverse the list from the beginning or from the end. The input to the function is a singly linked list, and the output is a boolean value indicating whether or not the list is a palindrome.

Given a singly linked list, this function returns the middle node of the list. If the list has an even number of nodes, the function returns the node at the start of the second half of the list.
