## Overview

Algo Deck is an open-source collection of +200 algorithmic cards .

It helps you preparing and succeeding in your algorithm & data structure interview . The code examples are in Java.

The topics covered are the following:

• Array : reversing an array, finding a pivot, handling a dynamic array, etc.
• Bit : operators, bit manipulation, etc.
• Complexity : algorithm & data structures complexity
• Dynamic Programming : dynamic programming concept
• Encoding : encoding theory
• General : general knowledge including how to approach a problem or testing a first solution
• Graph : A*, Dijkstra, BFS vs DFS, cycles detection, topological sort, etc.
• Greedy : greedy algorithms concepts
• Hash Table : hashtable data structure
• Heap : heap data structure including min-heap/max heap, binary heap use cases, etc.
• Linked List : linked list data structure, how to get the middle element, iterate over two lists, doubly linked list, etc.
• Math : discrete math
• Queue : queue data structure
• Recursion : recursion concepts
• Sort : sort algorithms including concepts, complexity, use cases, etc.
• Stack : stack data structure
• String : string permutation, rotation, rabin-karp substring search, etc.
• Technique : most important techniques to master to solve algorithmic problems including greedy techniques, runner, sliding window, etc.
• Tree : binary tree use cases, binary search tree, 2-3 tree, red-black tree, use cases, etc.

## Anki Deck

Anki is a free software (Windows/Mac/Linux/iPhone/Android) which makes remembering things easy. It utilizes spaced repetition which is a proven technique to increase the rate of memorization:

```The single biggest change that Anki brings about is that it means memory is no longer a haphazard event, to be left to chance. Rather, it guarantees I will remember something, with minimal effort. That is, Anki makes memory a choice.
```

Michael A. Nielsen, "Augmenting Long-term Memory"

Thus, using Anki is a great way to prepare your algorithm & data structure interview.

The Anki version (an Anki clone of the cards available in this repo) is available for \$12.99:
