C Program to Implement CockTail Sort



C Program to Implement CockTail Sort

This C Program implements cocktail sort. Cocktail sort is a variation of bubble sort that is both a stable sorting algorithm and a comparison sort. The algorithm differs from a bubble sort in that it sorts in both directions on each pass through the list. This sorting algorithm is only marginally more difficult to implement than a bubble sort, and solves the problem of turtles in bubble sorts.

The various names of cocktail sort are bidirectional bubble sort, cocktail shaker sort, shaker sort , ripple sort, shuffle sort, shuttle sort or happy hour sort
