Top 10 Interesting Data Structure Project Ideas for Beginners

Are you searching for beginner’s data structure project ideas? Do you want to know the best project ideas for data structure? Data structure is an important part of computer science. It refers to the format that includes the group of data values, their connections, and the important functions we can apply to the data. A “data structure” is defined as the organization and storage of data in a structured manner. The data structure is that part of computer science without which any program or function isn’t able to do work. 

In any computer science job profile, you must have complete knowledge of data structure because data management is very important for every computer scientist and engineer.  If you want to improve your data structure skills, you should work on data structure projects. 

Basic types of data structure

There are some important basic types of data structures that you should know of. That separates into so many types like:

Programming and problem-solving processes both depend on choosing the right setting for your data. Furthermore, data structures arrange abstract data types in their practical applications. They use a variety of algorithms, including sorting, searching, etc., to get that outcome. One of the key components of data science courses is learning data structures.

Top 10 Interesting Data structure project ideas for beginners

1. Obscure binary search tree

We can store a lot of information in BSTs (Binary Search Trees), including names, phone numbers, and other specifics. We can save some of the data in the database automatically, balancing their height as they add or remove. They also mention self-balancing BSTs because of this. They are of three types B trees, AV trees, and red-black trees. For a data structure project, this is the best idea because it will teach you the most. 

2. Time for heap insertion 

Heap insertion is the best project idea because it can improve your basic knowledge. When looking for data structure projects, you want to run into specific issues that are being tackled in novel ways. One such original research topic is the typical case insertion time for binary heap data structures. Some internet sources claim it is log (n) time, while others assert it is continuous time. Bollobas and Simon offer a quantitatively supported response in their paper titled “Repeated Random Injection into a Priority Queue.” They start by assuming that you wish to add n elements to an empty heap. 

3. K-d trees-based research project

The spatial data represents and organizes using K-d trees or K-dimensional trees. There are a ton of uses for that data structure tree, primarily in multi-dimensional key searches that function similarly to nearest range and neighbor searches. We now talk about the operation of key searches: 

  • Every binary tree’s node leaf refers to a K-dimensional point. 
  • Every non-leaf node separates the hyperplane into two different half-space parts which are perpendicular to the dimensions. 
  • We can describe the problems to the left of the hyperplane in the left subtree of a particular node. The problems represent the right subtree of that node in the right half.

4. Knight’s travails

You are familiar with the two algorithms used in this project, BFS, and DFS. BFS and DFS are the initials for breadth-first search and depth-first search, respectively. BFS uses the queue data structure and DFS navigates the stack data structure to determine the shortest path. You’ll need a data structure like a binary tree. One of the best project ideas for beginners on data structures is this one, which will help you expand your knowledge in a crucial area for you. This is one of the best data structure project ideas for beginners.

5. Search engine for data structure

The software aims to speed up and automate the selection of a data structure for a particular API. This project shows new ways to represent different data structures while also optimizing a set of functions to allow inference on different data structures. Below is a list of its highlights.

  • Understanding data structures and the connections between various methodologies is necessary for the data structure to search engine projects.
  • It calculates how long each potential composite data structure would take for all possible methods.

6. Fast data structures in non-C systems languages

Programmers typically create data structures in C/C++ by constructing programs in high-level languages like Ruby or Python. They also develop a binding code to link the components. The C programming language looks like it will be error-prone, which can also lead to security problems. We can create a data structure in a contemporary low-level language like Rust or Go, and then your code links to the high-level language. If your effort is successful, you might even motivate others to carry out a similar task in the future and promote better data structures that are performance-oriented. 

7. Contact directory application 

This project is one of the best data structure project ideas for beginners and this teaches you about data structures like arrays, linked lists, stacks, and queues as well as how to contact book applications operate. Typically, managing a contact book entails performing searches, sorts, and deletions. The distinctive feature of the search queries used here is that the user sees suggestions from the contact list after each character they enter. You can replicate projects that are freely available and read the source code to hone your skills. 

8. Spatial indexing with quadtrees

A unique kind of tree structure called a quadtree can recursively divide a flat 2-D space into four quadrants. We can accomplish many tasks, such as image processing, spatial indexing, and sparse data storage, using it. The efficient execution of specific geometric queries is what spatial indexing is all about, and it plays a crucial role in the design of geospatial applications. To track the location of cabs and update users, ride-sharing apps like Ola and Uber, for instance, process geo-questions. 

9. Graph-based projects

You can work on a project about graph topological sorting. You’ll need to be familiar with the DFS algorithm beforehand for this. This is best project ideas from the list of data structure project ideas for beginners. The main distinction between the two methods is as follows:

  • We print a vertex and then use DFS to repeatedly invoke the procedure on nearby vertices.
  • In topological sorting, the method for nearby vertices is first called recursively. The content is then pushed onto a stack for printing.

To return an array of nodes, the topological sort algorithm requires a directed acyclic graph or DAG.

10. Stack-based text editor

While the text is being written or edited, your standard text editor can edit and store it. As a result, the cursor’s position has changed many times. We need a quick data structure for insertion and change to achieve the most efficiency. Additionally, string storage in regular character arrays is time-consuming. To address these problems, you can experiment with different data structures like ropes and gap buffers. Your ultimate goal will be to use less contiguous memory space to achieve faster concatenation than the typical strings.
