Data structure - WikipediaBest article on data structure and algorithms. Your article helped me in my java interview. Tweet This. There are a lot of computer science graduates and programmers applying for programming, coding, and software development roles at startups like Uber and Netflix. Coding interviews are comprised mainly of data structure and algorithm-based questions as well as some of the logical questions such as, How do you swap two integers without using a temporary variable? Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews. Without any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews :.

If you wish, you can read through a seven-page course description. A page topic summary is also available: Algorithms and data structures—topic summary. This is a collection of PowerPoint pptx slides "pptx" presenting a course in algorithms and data structures. Associated with many of the topics are a collection of notes "pdf". Some presentations may be associated with videos "V" and homework questions "Q" , possibly with answers "A". You will note that the section numbering in the notes is paralleled in the top left corner of the slides; thus, anyone watching the slides can follow along in the notes. Before we proceed with looking at data structures for storing linearly ordered data, we must take a diversion to look at trees.
Post a Comment. In the last article , I have shared some of the best data structure and algorithms books for programmers, but those were not free. After that article, I received some feedback about how about sharing free data structure and algorithm books? Fair enough, everybody loves free eBooks, courses and PDFs, don't you? In the past, I have shared a list of free Java programming books, so I had some idea. I did some more research on the internet and checked my collection as well. Fortunately, there are a couple of good Data Structure and Algorithm books which are available for free as a PDF download or for online reading, which is what I am going to share with you all today.
While there are several basic and advanced structure types, any data structure is designed to arrange data to suit a specific purpose so that it can be accessed and worked with in appropriate ways.

In computer science , a data structure is a data organization, management, and storage format that enables efficient access and modification. Data structures serve as the basis for abstract data types ADT. The ADT defines the logical form of the data type. The data structure implements the physical form of the data type. Different types of data structures are suited to different kinds of applications, and some are highly specialized to specific tasks. For example, relational databases commonly use B-tree indexes for data retrieval,  while compiler implementations usually use hash tables to look up identifiers.
