Algorithm Visualizer

This is a sorting algorithm visualizer written in C++ using OpenGL. I learned a lot through this project whether it be setting up a C++ environment, installing 3rd party dependencies, or safe pointer practices.

The GIF above displays the following sorting 50 random numbers (1-100)

1. Bubble Sort
   • Average speed: O( n^2 )
   • Average memory: O( 1 )
2. Merge Sort
   • Average speed: O( n logn )
   • Average memory: O( n )
3. Quick Sort O( n logn )
   • Average speed: O( n logn )
   • Average memory: O( logn )

Of the three, quick sort is often seen as the best because it is more practical with it requiring less memory and having a better cache performance. Merge sort is prefered when stability is needed.

Things to note

• GLFW 3 Setup
• GLFW 3 Download
