Description

This C++ program implements the Cocktail Shaker Sort algorithm, a variation of Bubble Sort. It sorts a list of integers by traversing through the array in both directions—left-to-right and right-to-left—allowing it to quickly place unsorted elements into their correct positions. The algorithm continues alternating between these passes until no more swaps are needed, indicating that the array is sorted. This approach is particularly efficient for nearly sorted lists. The main function demonstrates sorting a sample array and outputs the sorted result.
