from arrays , link list ,queue to the Binary trees , Graphs and more

## What You Will Learn

#### LESSON 1

- Introduction and Efficiency
- Basic introduction to topics covered in this course.
- Leand the definition of efficiency as well as an explanation of the notation commonly used to describe efficiency.
- Practice describing efficiency with code snippets.

#### LESSON 2

- List-Based Collections
- Learn the formal definition of a list, see definitions and examples of list-based data structures, arrays, linked lists, stacks, and queues.
- Examine the efficiency of common list methods, and practice using and manipulating these data structures.

#### LESSON 3

- Searching and Sorting
- Explore how to search and sort with list-based data structures, including binary search and bubble, merge, and quick sort.
- Examine the efficiency of each and learn how to use recursion in searching and sorting.
- See and write examples of these methods, as well as more sorting algorithms like insertion sort.

#### LESSON 4

- Maps and Hashing
- Understand the concepts of sets, maps (dictionaries), and hashing.
- Examine common problems and approaches to hashing, and practice with examples of hash tables and hash maps.

#### LESSON 5

- Trees
- Learn the concepts and terminology associated with tree data structures.
- Investigate common tree types, such as binary search trees, heaps, and self-balancing trees.
- See examples of common tree traversal techniques, examine the efficiency of traversals and common tree functions, and practice manipulating trees.

#### LESSON 6

- Graphs
- Examine the theoretical concept of a graph and understand common graph terms, coded representations, properties, traversals, and paths.
- Practice manipulating graphs and determining the efficiency associated with graphs.

#### LESSON 7

- Case Studies in Algorithms
- Explore famous computer science problems, specifically the Shortest Path Problem, the Knapsack Problem, and the Traveling Salesman Problem.
- Learn about brute-force, greedy, and dynamic programming solutions to such problems.

### LESSON 8

- Technical Interviewing Techniques
- Learn about the “algorithm” for answering common technical interviewing questions.
- See how to clarify and explain practice interview questions using the concepts taught in this course, and get tips for giving interviewers exactly what they’re looking for in an interview.

#### LESSON 9
