Data structures and algorithms are essential in computer science since they play a crucial role in efficient information retrieval and processing, dealing with files, storing contacts on phones, social networks and web searches.

In this course, you’ll learn about the array-based implementation of various linear data structures, stack, and queues. You’ll also learn about linked list-based implementation. Next, you’ll explore advanced data structures like skiplists and hashing. You’ll learn how to implement a variety of trees and graphs, and data structures related to bits of an integer. Toward the end of the course, you’ll learn the implementation of structures based on external storage.

After completing this course, you’ll be able to create reusable programs with template-based collections that can efficiently analyze how to optimize the storage and retrieval of very large amounts of data. Overall, this course will enhance your productivity and performance as a software developer.

Data Structures with Generic Types in Java

 A red-black tree with $n$ nodes has a height of $n$.

The `add(x)` and `remove(x)` operations on a red-black tree run in $O(n)$ worst-case time.

The amortized number of rotations performed during an `add(x)` or `remove(x)` operation is constant.

The height of a red-black tree with $n$ nodes is always $2\log(n)$.

What is a property of red-black trees?

Red-black trees have a height of at most $2\log n$.

The `add(x)` and `remove(x)` operations on a red-black tree run in $O(\log n)$ expected time.

The number of rotations performed during an `add(x)` or `remove(x)` operation is proportional to the number of nodes in the tree.

Red-black trees have a height of exactly $2\log(n)$.

Which statement about red-black trees is *true*?

Which statement about red-black trees is true?

Which property is satisfied by the left-leaning red-black trees?

Which property is satisfied by the left-leaning red-black trees?

It does not change the black height of any node.

Which statement about the `add(x)` operation for a `RedBlackTree` is *true*?

Which statement about the <code>add(x)</code> operation for a <code>RedBlackTree</code> is true?

Test yourself on what you've learned about red-black trees.
