Conclusion We hope you're now feeling confident with the basics of Arrays! Because practice makes perfect, here are a few more practice problems for you! What's Next? Let's recap what we looked at in this explore card: We explored what the Array data structure is all about. We looked at the Java syntax for creating Arrays. We looked at the Java syntax for reading and writing from Arrays. We desi..
In-Place Operations Now that we've got all the basic Array operations out of the way, we're going to have a look at in-place Array operations. These are very important from an interviewing standpoint. In-place Array operations are where we modify an Array, without creating a new Array. We've already seen some examples of this: inserting and removing items by shifting existing items along. There ..
Inserting Items Into an Array In the previous chapter, we looked at what Arrays are, and the basic programming constructs of Arrays in Java. We're now going to use these basic constructs to implement three key operations for Arrays: Inserting items. Removing items. Searching for items. These three operations are the fundamental operations for all data structures. In this chapter, we'll be starti..
Introduction to Data Structure Overview Introduction Arrays are a simple data structure for storing lots of similar items. They exist in all programming languages, and are used as the basis for most other data structures. On their own, Arrays can be used to solve many interesting problems. Arrays come up very often in interview problems, and so being a guru with them is a must! In this Explore C..
