9.0 Data Structures – Advanced Lists .. Part-2

Let's continue talking about Lists, but first let's have a quick recap. In the last post, we covered a new way to implement lists, which is using recursion. To use this technique, we changed the underlying data members. In this post, we are continuing with another version of lists, Circular Lists. The idea behind circular …

8.0 Data Structures – Advanced Lists .. Part-1

In the previous posts, we have discussed Lists. We discussed how to implement them using array, using linked nodes and how to create sorted lists. In this post, I'm gonna discuss some advanced tips in implementing lists. Before continuing reading, make sure to revise the past three posts about lists to get the big picture. …

7.0 Data Structures – Binary Search Trees

A tree is a data structure that has many variants.  From our human perceptive, trees have too many branches and leafs. They are very useful in sunny days, where we walk under their shadows. In Computer Science world, they have another usage. We use their leafs to store data. Yes!! their leafs are a place where we can …

6.0 Data Structures – Stacks

A Stack is one of the most important data structures that are used in computer programming. It has many variations in its implementations. It also plays very important roles in operating systems implementation and programming languages capabilities. To connect topics with each other, we have discussed Queues in the last post. We have seen how …

5.0 Data Structures – Queues

Queues !! A word that we hear every day. Not only we hear that word, but also we do live it. How can a queue then be a data structure that is used in computer programming ?! Let's See. In the last post, we have wrapped up talking about lists. We saw how they are …
