Data Structure And Algorithm For Interview Preparation[Java]

Description
This course mainly focuses on problem-solving using Data structures and algorithms in Java. Why DSA?A person who has strong DSA skills will have a better and more efficient way of solving problems. A lot of software companies conduct DSA rounds to test a candidate’s problem-solving and coding skills.Big companies like Google, FaceBook, Amazon, PayPal, Microsoft, etc ask DSA questions in most of their coding rounds.DSA skills are required for competitive coding and for clearing online coding interviews from Hackerrank, Hacker earth etc.Why DSA skill is asked in interviews?Big companies like Facebook and Google can’t ask you about the technologies required for work because they’re proprietary. People who haven’t worked at Google haven’t ever seen the technologies they’ll be using because they don’t exist outside of Google. You can’t effectively test someone on something they have no way of knowing.So instead you want to test people on how smart they are, how good they are at solving problems, and how quickly they can pick up new technologies. This is very difficult to test in an hour, so algorithms and data structures are used.How this course is structured?This course uses Leetcode questions to demonstrate how problems can be solved using DSA. Some of the famous interview questions are taken and solved topic-wise. Debugger is used to demonstrate the code flow in Leetcode. What are the topics covered in this course?Basics of Data structures – what are arrays, strings, sets, lists, maps and how to declare, iterate and access them.ArraysStringsLinkedListStackDepth-first searchTreeTopics – Graph, Dynamic programming, and backtracking will be added shortly in a few weeks
