Data Structures & Algorithms

00:05:00

The Data Structures and Algorithms Course is tailored for individuals in the software engineering field who aspire to elevate their careers by securing interviews with some of the world's most prestigious companies. This program is meticulously designed to equip you for these crucial interviews, covering a comprehensive range of skills, from problem-solving techniques to coding proficiency. You'll gain invaluable hands-on experience by tackling over 100 data structures and algorithm problems. The course commences with problem-solving exercises related to each data structure and algorithm, preparing you thoroughly for interviews with top-tier product-based companies such as Meta, Microsoft, Amazon, Adobe, Netflix, and Google.

Participants in this training will learn data structures and algorithms course and at the completion of this course, attendees will be able to:

- Identify techniques to design algorithms and measure their efficiency.
- Sort data by using bubble sort, selection sort, insertion sort, shell sort, quick sort, and merge sort.
- Search data by using linear search and binary search techniques.
- Store and search data using hashing.
- Solve problems using arrays, lists, linked lists, queues, and stacks.
- Solve problems using non-leaner data structures like trees, and graphs.

Thanks a lot for arranging such Technical training's and would like to join more such training's with Scholarhat. Training is lead by a great teacher "Shailendra" . Training has been great learning curve for me and I am still learning and going through the shared videos to capture things which I have missed.

It was very good experience getting Azure DevOpsTraining with ScholarHat. Dot net tricks a unique training institute for new updated technology Azure. Mr. Shailendra Chauhan sir always teaches the latest technologies. Thanks, ScholarHat for teaching me in-depth practical concepts.

Scholarhat has brought a new revolution in e-learning which reform the way of learning. Scholarhat training best ever training i have gone through. It's compliantly changed my programming approach while developing software application. i'm feeling proud while writhing this testimonial.

I believe that Scholarhat is the best place for learning and updating ourselves moreover overcome from all issues that are face during development ...!! I come to know about Scholarhat innovative way of providing real time project based training in 2014 through one of my friend who have taken class from Scholarhat, during that time I started my career as a UI developer, my friend who have taken training in Angular JS working with HCL technology. Now after one and half year I have been looking for changing my job profile so that I have joined Scholarhat again for updating MEAN Stack Developer. Few words to Shailendra Sir, Thank you very much sir for giving me a precious guidance by explaining through various real world scenario.
