An ordered list is one which is maintained in some predefined order, such as alphabetical or numerical order. We’ll study a linked list implementation. delete an element from the list. We’ll also consider lookup, a routine to extra information from the list. So the following list is ordered (in ascending order). But the following list is not.

Our basic linear data structures — arrays, linked lists, vectors — can be used for ordered data. We keep the data in sorted order (i.e., the first or highest priority item is first). Let’s focus on the efficiency of the following operations.

Oct 16, 2024 · Data structures store the ordered data so that different kinds of operations can be performed easily. In this article, you will get complete details about the data structure reference books, study materials, and Lecture Notes.

Basic Operations on Lists • Inserting a Data Item (at beginning, at end, or elsewhere) • Deleting a Data Item (at various list positions) • Sorting (alphabetically, numerically; in ascending or descending order) • Searching (for specified data item or set of items, or for those satisfying certain conditions) • Copying

• Sequence – an ordered collection of items (position matters) • we will look at several types: lists, stacks, and queues • Can represent any sequence using an array or a linked list

list: a collection storing an ordered sequence of elements. -Each item is accessible by an index. How do Java / other programming languages implement ArrayList to achieve all the List behavior?

•Sequences are ordered sets. •In sequences, it makes sense to talk of: –first element, second element, last element. –previous element, next element. •In sets, order does not matter. 3

Ordered Lists • An ordered list is kept in order based on characteristics of the elements in the list, e.g. alphabetical order for names • The class for objects kept in an ordered list must implement the Comparable interface • When an element (object) is added to an ordered list, its position relative to the other

For example, [10, 20, 30, 40] Here is an ordered list. How did the elements get into the list? Why are they in this particular order? Which element is at the start of the list? Which element is at the end of the list? What operations should we provide for our ordered list ADT???
