About this Free Download Course

Course 50 Days of DSA JavaScript Data Structures Algorithms LEETCODE. The main purpose of this course is to prepare you for coding interviews in top technology companies. By solving one problem at a time and understanding the solution, you’ll gather a set of tools and techniques to ace any coding interview. Daily coding challenges of data structures and algorithms: This course is designed around daily coding challenges. Consistent practice will equip you with the skills necessary to succeed in coding interviews. For the next 50 days, commit to practicing at least 2 coding interview questions per day. No setup is required for this as daily coding problem challenges can be solved in the coding environment provided by Udemy. The course automatically tracks your progress and you just have to spend your time making actual progress each day. Topics Covered: We start with the basics with Big O analysis, then move on to very important algorithmic techniques such as recursion, tracing, and dynamic programming patterns. After that, we move on to common data structures and discuss real problems asked in interviews at tech giants like Google, Meta, Amazon, Netflix, Apple, and Microsoft.
