Quicksort is a highly efficient sorting algorithm that utilizes a divide-and-conquer strategy to sort elements in an array or list. By selecting a 'pivot' element and partitioning the other elements into two sub-arrays, one with elements less than the pivot and another with elements greater, quicksort recursively sorts these sub-arrays. Its efficiency makes it a popular choice for large datasets, emphasizing the importance of understanding sorting algorithms in data structures and abstract data types.
congrats on reading the definition of quicksort. now let's actually learn it.
