Data Structures & Coding Interview Algorithms
Below are the features of this App:
1. Collection of ~400 Coding Interview Problems & Solutions
2. Detailed explanation of various Data Structures and Algorithms
3. Algorithmic complexities for various Data Structures and Algorithms
4. Frequently Asked Questions
5. Quiz with ~500 questions
The Algorithms are from the following topics.
* Arrays
* Strings
* Two Pointers
* Linked Lists
* Trees
* Depth First Search
* Breadth First Search
* Graphs
* Tries
* Hashing
* Stack
* Heap
* Dynamic Programming
* Back Tracking
* Implementation
* Math
* Sorting
* Searching
* Greedy
* Bit Manipulations
* Divide and Conquer
* Union Find
* Topological Sort
All the algorithms and data structures are implemented in Java. Some of the solutions are my own implementations. For the remaining problems I have chosen the most preferred & popular answers from various resources on the Internet.
Good luck :)

Great app, I wish there was a way to provide user feed back on each algorithm. e.g some algorithms can be optimized. Take 2 sum for instance. you should only have to traverse half the numbers to find a match.
Fantastic app! Great UI and great content! Many code examples! Only flaw is a little bit of performance lag when selecting things.
This app has an amazing variety of questions. Although the solutions are great bt i think the solution shud have some links as well since its really difficult to understand the solutions by the five lines given for hard and medium problems.
High-level, comprehensive reference geared. Largely descriptive in nature, no proofs are put forth and there little investigation into the statements asserted. Very useful as a documentation, less so as an educational tool.
One of the best apps. However for learning data structures, I would recommend another app. This is for those who understand the concepts clearly.
I searched for many apps to learn DSA. This is by far the best app. it almost has all questions which could be asked in an interview with proper solutions. Blindly go for it!
I have absolutely no clue how to program algorithms, but the way the information is presented and laid out makes me want to. I especially like the step by step approach (with comments).
content is good but there should be a search feature which can search from all coding exercise.
Go for it ! Review coding ...... Questions are structured in a clear manner. Solutions to questions are the best manifestation of algorithm designing. Download now !
Just browsing through seems like it contains everything I hoped for in an app to help prepare for interview. Great list of questions and good review of big O complexity too
Nice app if you wanna practise data structure. It will brush up your concepts and you will get familiar with each type of questions Thanks developers to make such a nice app Your work is appreciated
Best app ever..recommend to everyone.. solutions based on java and the soltions are optimal solution with regards to time and space...
Provides concise and clear facts. UI is clean. Keep up the good work.
Actually this one is very good and useful but you should consider about adding a search function.. keep the good work up..
Thank u developers. Very handy. Is there a companion website or source code? Sometimes I like to read on a desktop.
Not a beginner app at all. I'm sure it's great if you're heavily experienced on this topic.
your app is great, really good content....a suggestion please allow us to sort the question according to difficulty. just that
This is an absolutely awesome application. It is indeed a wise choice to learn programming from here. Thank you so much. Love it.
Quizzes are fun way to learn on the go, waiting in line, eating, etc...
Great app with lots of questions and answers. Great for campus placements.
This app is wonderful. I prepared for Amazon using this app and now I got the internship there, a vast variety of problems are covered.
Simple and elegent + good set of problem, Author, can u point me to your website or share all these problems docs with, its hard to follow up code in mobile screen
what a great UI and best algorithm and problems, that definitely helps in improving programming skill😍
Very concrete and one place to find most asked questions. Would definitely recommend it.
Excellent Application Even For Beginners and Keep Learning All The Key Concepts From this App to Overcome Your Hurdles in Data Structures.... Thank You So Much Team ❤️
It's a good app and there are very good questions and good explanation solutions 👌simple UI👌.
Rocker app. Night mode (dark background, white text) will make this best app in playstore
Easy to inderstand, and this app is helpful for whos students those prapering ds and algo.
Such a great app for keeping important questions in mind. Please release for iOS as well.
The app is complete in itself by providing solution for almost all the famous problems. And the ad free version of it has made the learning doubly enjoyable, but i would rather download some extra megabytes of data than to download the singular problem solution again and again everytime, and as demanded by others a search functionality would be a win-win definitely. Thank u for bringing great stuffs to us...
