Data Structure is a particular arrangement of data used by computer programs to bring efficiency in execution. There are many types of data structures which can be broadly classified into *linear* or *non-linear* data structures.

The linear data structures are array, linked-lists, etc., and non-linear data structures are a tree, graph and so on. We intend to cover following topics in this tutorial.

## About Data Structure Tutorial

There is no prerequisite to learn from this tutorial. But some experience with programming languages such as C/C++ can be helpful.
