// Given a linked list, find and return the midpoint. // If the length of linked list is even, return the first mid point. // Input format : Linked list elements (separated by space and terminated by ...

Like arrays, which were introduced in Part 3 of this tutorial series, linked lists are a fundamental data structure category upon which more complex data structures can be based.

A linear data structure traverses the data elements sequentially, in which only one data element can directly be reached. In other words, you can travel along a linear data structure in one direction ...

I’ve focused on two data structure categories, Java arrays and linked lists, which are the basis of more complex data structures such as stacks, queues, trees, graphs, dictionaries/maps, and sets.
