About this app

The application provides comprehensible content on the study of computer algorithms with a focus on interactivity and visualization of each step. By using controls the user goes through the algorithm while observing its work.

The current version of the application covers the following basic computer algorithms and data structures:

I. DATA STRUCTURES
- Array,
- Linked List,
- Stack,
- Queue

II. SORTING

- Bubble sort,
- Selection sort,
- Insertion sort,
- Merge sort,
- Heap sort,
- Quick sort

III. BINARY SEARCH TREE

- Pre-order traversal,
- In-order traversal,
- Post-order traversal,
- Breadth-first traversal,
- Inserting and deleting a node in Binary Search Trees (BST),
- Inserting and deleting a node in Self-Balancing Trees (AVL and Red-Black Trees)

IV. HASH-TABLE (chaining technique)

- Inserting data into a Hash-table,
- Deleting data from a Hash-table

V. GRAPH

- Depth-first search,
- Breadth-first search,
- Minimum Spanning Tree,
- Dijkstra's algorithm,
- Graph Constructor

The visualization of the algorithms and data structures is accompanied by a piece of code that shows its implementations. There is a direct link between the code and the visualization. The full code of each algorithm can be found by the link to a third-party Internet resource. Although the given code is written in Java and Python, the explanation and visualization of the algorithms are in no way tied to a specific programming language.

Algorithms and Data Structures Interactive Course is designed for a wide range of users and does not require any programming skills to understand this or that algorithm. The app may also interest experienced programmers, as it enables users with quick and efficient revision of the above algorithms.

The advantage of Algorithms and Data Structures Interactive Course in comparison to other numerous resources for learning algorithms (books, presentations and videos), is that it helps master the material with minimal waste of time since while the user is observing the visual effect at every step, he or she is being involved in the algorithm. There is no need to pause or rewind in order to comprehend the idea of a lecturer as it happens with video-content. The speed of advancement in the Algorithms and Data Structures Interactive Course training program depends on the pace of the user, and not on the speed of a video clip.

Excellent app, great value! I'm a professional engineer, but learned mostly on the job, so I have a lot of gaps around algo/data struct/big O. I've been trying to learn and be able to name them all, and this app is awesome! What completely sold me on getting full access was the light bulb part on slide 17 of Arrays. That kind of granular information really helps me cement things together and it was wonderful to see that!

I loved the app and the the way it explains you. But I came across the double linked list and found it to be different than what I was taught( a double linked list has 3 elements in each node previous,data and next). I wasn't sure so here I am.

Thanks for your feedback! The fact is that the application considers a regular linked list and a double-ended linked list (when we have access to the first and last element), but a list where each element has a link to the previous and subsequent element (a doubly linked list) was not considered. Perhaps this list will also be added in the future.

I've tried several apps to help visualise different algorithms and this one is definitely the best - interactive and explains things well. Absolutely worth the £1.80 to unlock everything!

Thanks for appreciating the value and for your support!

What's new

The presentations for Depth-First Search (DFS) and Breadth-First Search (BFS) graph traversal algorithms have been redesigned to enhance the learning experience.
