that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared to that for the LinkedList implementation.

快速排序是高效的排序算法，通过分治策略，将大问题分解成小问题解决，平均时间复杂度为O(n log n)。How to implement the quicksort algorithm in Java:Select the pivot: At the start of quicksort, an element from the array is chosen as the pivot (usually the first element or the last element)....
int[]numbers={3,2,1};Arrays.sort(numbers);System.out.println(Arrays.toString(numbers));// Output:// [1, 2, 3] Java Copy In this example, we useArrays.sort()to sort an array of integers. The output shows the array sorted in ascending order. ...
/ 2 = n^2 / 2 + n / 2。 3，根据 大O推导法 可以知道，此时时间复杂度为 O(n^2)。
