Description

Want to land a software engineering job in the IT industry? This course - 'Visualizing Data Structures and Algorithms in Java' is here to help. The course walks you through multiple Java algorithms, data structures problems and their solutions with step by step visualizations, so that you are actually learning instead of blindly memorizing solutions.

The course covers in and outs of Data Structures and Algorithms in Java. Java is used as the programming language in the course. Students familiar with Javascript, Python, C#, C++, C etc will also get to learn concepts without any difficulty. The implementation of various Algorithms and Data Structures have been demonstrated and implemented through animated slides. It covers many interview room questions on Algorithms and Data Structures. The questions and solutions are demonstrated by -

1. Animated slide. (To make visualization of algorithms faster)
2. Coding algorithm on IDE.
3. Source code

The course covers topics such as -

1. Arrays
2. Matrix
3. Singly Linked List

I tried to find some good courses on data structure and algorithm but none of them were very clear. This is one of the best course I have come across on the udemy. The instructor has explained each and every program in a detailed manner and it gives you the answer 'WHY?' this particular logic is written. He is very supportive and solves all your doubts in the Q&A section. Thank you for this wonderful course. Looking forward for more content and more course from the instructor.
