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.

IDG. Figure 2. The initial singly linked list consists of a single Node (A) This operation has a time complexity of O(1)–constant. Recall that O(1) is pronounced “Big Oh of 1.” (See Part 1 ...

Analyze the time and space complexity of your solution. Compare your solution to others and identify areas for improvement.

The Java Platform provides the most commonly used data structures in the form of the Collections Framework, and it provides a rich API to operate on them. This article explains the concepts behind ...
