Sorting Algorithm Examples

This is a collection of programs implementing a wide variety of sorting algorithms. The code has been optimized for speed instead of readability. You will find them to perform better than the perspective standard algorithms. The Combo Sort should be suitable for production usages.
These examples were constructed by studying the following text books:
  1. Robert Sedgewick, "Algorithms in C"
  2. Mark Allen Weiss, "Data Structures and Algorithm Analysis"
  3. Tenenbaum, Langsam, Augenstein, "Data Structures Using C"
Skip Navigation Links Exchange two adjacent elements if they are out of order. Repeat until array is sorted. This is a slow algorithm.
