Description
Your Search on Learning Data Structures & Algorithms ends here. Ds & Algos are very easy if you know how exactly they work! And I am here to show its implementation process with very easy approach using Whiteboard teaching so that you will master on all the essential concepts to clear the Interviews.The examples I picked in this course will fine tune your thought process and enhance your logical thinking ability. With the approach of Whiteboard teaching, You will have practical understanding of how Data structures Problems can be analyzed and solved!!There are tons of Assignments & Interview Questions with solutions all over the course for practice so that you can progress in the course confidentlyIn this course, I use Java to teach the concepts but you can apply these concepts in any programming language. Our focus is on data structures and algorithms, not programming languages and tools.Below are the list of Data Structure topics you will master from this tutorial1. Recursion2. Linked List3. Stacks4. Queues5. Time Complexity6. Search Algorithms7. Sort Algorithms8. Binary Trees9. Arrays & Heaps10. Hash Map with its internal working processBy end of this course, you will gain enough confidence in solving the Data Structure puzzle questions and also gain the ability to write algorithms for any given problem
