This FREE App is developed to assist the programmers in their Technical and Coding Interview preparations. This can be used by both experienced developers and students.

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 :)
