Dual-Pivot QuickSort is an efficient sorting algorithm that improves upon the traditional QuickSort method. It uses two pivot elements instead of one, which allows the algorithm to partition the array into three sections: elements less than the first pivot, elements between the two pivots, and elements greater than the second pivot. This approach can lead to fewer comparisons and swaps, enhancing performance. The algorithm works recursively, applying the same partitioning strategy to the resulting subarrays. Dual-Pivot QuickSort is particularly effective for large datasets and is often used in programming languages like Java for its built-in sorting functions, making it a popular choice for developers.
