AlgoPrep - Algorithms & Data structures Made Easy

Are you a Computer science/IT/ programming student or preparing for a Software Engineer interview ?

This tool will help you to see how the following algorithms will sort a set of numbers
1. Bubble sort
2. Improved bubble sort
3. Insertion sort
4. Selection sort
5. Quick sort
6. Merge sort
7. Heap sort

You can see how the sorting algorithm works step-by-step, real time visualization of the sorting and the different cases of time complexity of the algorithm.
(Best case, Worst case and Average case)

Sorting algorithms can be compared on an input and see the comparison in terms of comparisons, swaps and time required to sort.

On a set of cities data, we have built an interface where you can compare linear search and binary search for searching a string from the data.

Also, go through some data structures like stacks, linked-lists, queues, trees and understand how it works.(More updates to come in future)

So why just check pseudocode online ? See how it plays with the numbers visually.

** NO INTERNET CONNECTION NEEDED **

Great Content! I loved the stepwise breakdown of algorithms. After reading the steps, and then looking at the visualizations made it a lot more intuitive for me. Thanks!

Its a great app. The UI is great and to top it off, its made for one handed use! As a developer myself, I know how much hard work you and your team have done to make this wonderful app. Kudos to you! However, there's a small error. In every algo, space complexity is wrong. I think you meant to write auxiliary space complexity rather than space complexity. Also, it would be great if you could add some security based algos. Altogether, an app worth keeping. Eagerly waiting for further releases!

It has the potential to be a great algorithm learning tool. Unlike the others this allows the user to input information, shows a step by step process then gives output data, fast and efficiently. Simple and organized UI , making it easy to navigate and access the information given. The only problem IT LACKS INFORMATION! If there were more detailed information given, or FAQ for beginners in the options colemn, I would give 5/5 stars.

This app literally blew my mind🤩! I'm a visual learner so this really helped me in visualising common algorithms step-by-step & their runtimes. It also explains abstract data structures well. I highly recommend it to anyone wanting to master algorithms & data structures quickly & comprehensively. A huge thanks to the dev(s) behind this masterpiece.

Very useful. It would deserve more downloads. An improvement could be done on the pseudo-codes. Also some datastructure sections force their way to rotate the screen even if the rotation is disabled.

Superb app.visualusation makes it understand easily . Please add array, dynamic programming, heap as well

Pog. P. Jan 16, 2021     

It's ok. Clear animation of algorithms. Some fundamental errors in the information, which is bad for learners e.g. best case for bubble sort is given as O(n^2), which is incorrect. It is actually O(n). If the errors were fixed I'd give it 4.

Pranit Krishna Kulkanari put a lot of thought into developing this tutorial on the basic fundamentals of algorithms and data planning or structuring. Instructing people through a computer screen is quite challenging and just in the last ten to twelve years have I felt optimistic that interactive non-instructor learning via the internet and its various technologies, such as this excellent app, could become an effective manner in which to learn and develop skills. AlgoPrep is Playstore's best app.

This one was quick and excellent...straight to get concept in an abstract manner. After understanding how things work visually...anyone can implement it. Also being an android developer ...can say this app has fluid aesthetics and good material design. Good work by developer.

Nice visual explaination..it would be better if it had code for data structures too.

Joh. O. Jan 3, 2022     

Great app with fantastic options, really breaks algorithms and data structures down in a great visual way,easy to understand!!!

Abh. A. Jul 4, 2021     

Excellent app designed for free. I really love this app and its real time visualisation of all algorithms. Real time visualisation will help you understand the method more easily. I really credit a thank and gratitude towards the creator of this App.

reh. s. Jul 14, 2021     

Great app while I was searching for. Nicely swapped step by step. We can get sorted list by putting values as our requirements also it provides algorithm of a particular problem.

Ant. A. Dec 16, 2020     

A must have for app for someone learning data structure. Totally in love with the content. The step by step animation of sorting and graph traversal helped me understand the concepts well.

Zaf. H. Jul 12, 2020     

It is a good app to visualize. One suggestion is to add brief description to provide some context about algorithm and data structures being visualized.

Jos. K. Sep 11, 2021     

super slick app. really helps me understand the algos. A lot of cool features like manually putting in an array and then choosing the algo to use. Very nice =)

Sat. K. Oct 1, 2019     

Best app on algorithms. Can use some intuitive animations to increase visualisations. Please add more advanced algorithms.

MOH. S. Oct 24, 2020     

it's an awesome app for beginners to learn data structure and algorithms, visualise the concept for each and everything in sorting and searching algorithms

Ana. P. Oct 12, 2018     

Being an Android Developer myself I understand the hard work done here. Well designed and nicely managed large set of data within crashing it is awesome.

A. G. u. Nov 27, 2018     

This app is really awesome but in searching tab(Linear vs Binary), when I enter space before city name or after city name then it gives me no results.

A great tool to help visualize the way data structures work. Unfortunately this app ****does not teach users the code required**** to create or traverse the data structures listed. Highly recommend improving the app description to make it clear that it is not intended to teach users how to code.

Ken. O. Apr 21, 2021     

UI and UX are both good. It has a very cool approach to teaching the algorithms. Very cool.

Mon. K. Jul 22, 2021     

Best to revise the concepts in a short period of time.. I liked the realtime visualisation and stepwise display..

Lui. A. M. C. Jun 23, 2021     

Excellent experience, this app has all the algorithms for free and well explained. May be need to add more algorithms but I'm happy with this app

Sha. A. Oct 14, 2021     

This is the most amazing algorithm learning platform ever. Thank for aiding My understanding of algorithm. I recommend this application for all programmers.

imr. k. Jul 29, 2020     

Awesome aap for visualisation and comparison but it need improvement to give user a complete concept for the topic.

Moh. A. May 19, 2022     

It's really very helpful apps for understanding DSA.

Ste. B. Aug 16, 2021     

This app is amazing! It contains everything i ever wanted for an app like this. Simulations, pseudocode, explanations, complexities, etc.

SUB. C. May 6, 2021     

It's a good app for learning .. it will better if you add all algorithms like traveling salesman, prims....... Plz do the needful
