Linked-List: You can only read one element at the same time.
Memory Map: Allows direct access to all data.
Optimization: There are 2 key points to optimize:
Point 1: Find out the center of the list.
Point 2: Reverse the ordering of the second half of the list and compare it with the first half.
The diagram illustrates two examples with nodes that show how you would first read all data (in the Linked-List), then direct access allows you to compare elements starting from the ends towards the center (in the Memory Map). For optimization, the steps include finding the center of the list, reversing the order of the second half of the list, and then comparing the two halves to determine if the list is a palindrome.
