Sorting Visualization and Audibilization

Latest Update2 (05/04/2019)

Great News: Now we can get the Voice of Sorting Algorithm simultaneously, and this is so funny that we should all have a try!!!

Latest Update

Add three more sorting algorithms: CombSort, RadixSort, MonkeySort
Now you can record the whole sorting procedure to *avi videos.
Adding -r in command line can get you Re-sampled data.
Adding -s in command line can get you Sparse data.

Introduction

This repository is a demo of visualizing 12 types of Sorting Algorithms. It aims to make Sorting Algorithms easier for programmers to understand. Also, you can see the difference of Time Complexity between different sorting algorithms.

Sorting Algorithm	AverageTime Complexity	Bad Time Complexity	Stability
Bubble Sort	O(N^2)	O(N^2)	YES
Insertion Sort	O(N^2)	O(N^2)	YES
Shell Sort	O(N^5/4)	O(N^2)	NO
Selection Sort	O(N^2)	O(n^2)	NO
Heap Sort	O(NlogN)	O(NlogN)	NO
Merge Sort	O(NlogN)	O(NlogN)	YES
Quick Sort	O(NlogN)	O(N^2)	NO
Bucket Sort	O(N)	O(N)	YES
Cycle Sort	O(N)	O(N^2)	NO
Comb Sort	O(N^2)	O(N^2)	NO
Radix Sort	O(N)	O(N)	YES
Monkey Sort	O(N!)	O(N!)	YES
