Why Do We Need Data Structures?

In this course, we will focus mainly on data structures. However, algorithms and data structures go hand in hand with each other. Algorithms use data structures to manipulate the data effectively.

We can define a data structure as one that can store some logically connected data so that this data can be processed efficiently. And it is very important to have a way to process large amounts of data efficiently because if we have a lot of data, it often takes a lot of time to process it if the data is unstructured.

But how can we assess the quality improvement of our algorithm with the usage of the right data structure? That's what we will talk about in the next chapters.
