By BYJU'S Exam Prep

Updated on: September 25th, 2023

Data Structure & Programming is a very important subject as it covers all the basic concepts that are used in the Computer Science branch. This subject is full consists of the programming techniques which are required at the highest priority in the Computer Science field. It also carries a good amount of weightage in the GATE CS exam and all PSU exams. Also, many questions are asked from this subject in interviews of both the public and private sectors.

So, here, we are providing a list of important topics of the Data Structure asked in GATE and Computer Science engineering exams. While preparing for this subject, we advise you to not miss any of these topics because they are asked for the maximum time in GATE and other exams.
