Detailed Analysis

CourseMarks Score®

9.8 / 10

CourseMarks Score® helps students to find the best classes. We aggregate 18 factors, including freshness, student feedback and content diversity.

Freshness Score

10.0 / 10
This course was last updated on 6/2022.

Course content can become outdated quite quickly. After analysing 71,530 courses, we found that the highest rated courses are updated every year. If a course has not been updated for more than 2 years, you should carefully evaluate the course before enrolling.

Student Feedback

8.7 / 10
We analyzed factors such as the rating (4.5/5) and the ratio between the number of reviews and the number of students, which is a great signal of student commitment.

New courses are hard to evaluate because there are no or just a few student ratings, but Student Feedback Score helps you find great courses even with fewer reviews.

Content Score

10.0 / 10
Video Score: 10.0 / 10
The course includes 21h 32m video content. Courses with more videos usually have a higher average rating. We have found that the sweet spot is 16 hours of video, which is long enough to teach a topic comprehensively, but not overwhelming. Courses over 16 hours of video gets the maximum score.
The average video length is 9 hours 11 minutes of 134 Data Structures courses on Udemy.
Detail Score: 10.0 / 10

The top online course contains a detailed description of the course, what you will learn and also a detailed description about the instructor.

Description

This course is about data structures and algorithms. We are going to implement the problems in Java. The course takes approximately 14 hours to complete. It is highly recommended to type out these data structures several times on your own in order to get a good grasp of it. 
Section 1:
•data structures and abstract data types
Section 2 – Arrays
•what are arrays
•what is random access and how to indexes
Section 3 – Linked Lists
•linked lists and doubly linked lists
•linked list related interview questions
Section 2 – Stacks and Queues:
•what are stacks and queues
•heap memory and stack memory
•visualizing stack memory
Section 3 – Binary Search Trees (BSTs):
•what are tree data structures?
•how to achieve O(logN) logarithmic running time?
•binary search trees
Section 4 – AVL Trees
•what is the problem with binary search trees?
•balanced search trees: AVL trees
•rotations
Section 5 – Red-Black Trees
•what are red-black trees?
•what is recovering operation?
•comparing AVL trees and red-black trees
Section 6 – Splay Trees
•splay trees and caches
•achieve O(1) running time for getting the recently visited item
Section 7 – Heaps and Priority Queues
•what are priority queues?
•what is heap data structure?
•how to do sorting in O(NlogN) with heaps?
Section 8 – B-Trees
•external memory and the main memory (RAM)
•B-trees and their applications in memory
•B* trees and B+ trees
Section 9 – Hashing and HashMaps:
•what are hashing and hashtables (hashmaps)
•what are hash-functions
•how to achieve O(1) running time complexity
Section 10 – Sorting Algorithms
•basic sorting algorithms
•bubble sort and selection sort
•insertion sort and shell sort
•quicksort and merge sort
•comparison based and non-comparison based approaches
•string sorting algorithms
•bucket sort and radix sort
Section 11 – Substring Search Algorithms
•substring search algorithms
•brute-force substring search
•Z substring search algorithm
•Rabin-Karp algorithm and hashing
•Knuth-Morris-Pratt (KMP) substring search algorithm
Section 12 (BONUS):
•what is LRU cache
•LRU cache implementation
Section 13 (BONUS):
•Fenwick trees (binary indexed trees)
•binary indexed tree implementation
In each chapter you will learn about the theoretical background of each algorithm or data structure, then we are going to write the code on a step by step basis in Eclipse, Java.
Most of the advanced algorithms relies heavily on these topics so it is definitely worth understanding the basics. These principles can be used in several fields: in investment banking, artificial intelligence or electronic trading algorithms on the stock market.

Software Engineer
My name is Balazs Holczer. I am from Budapest, Hungary. I am qualified as a physicist. At the moment I am working as a simulation engineer at a multinational company. I have been interested in algorithms and data structures and its implementations especially in Java since university. Later on I got acquainted with machine learning techniques, artificial intelligence, numerical methods and recipes such as solving differential equations, linear algebra, interpolation and extrapolation. These things may prove to be very very important in several fields: software engineering, research and development or investment banking. I have a special addiction to quantitative models such as the Black-Scholes model, or the Merton-model.
