Bubble Sort: Simple but not very fast for large arrays. Merge Sort: Efficient and divides the array into smaller parts, sorting them before merging. Quick Sort: Fast on average, using a pivot to divide the array into smaller subarrays. Each method has its pros and cons, but understanding ...
定义:归并排序(Merge Sort)是建立在归并操作上的一种有效的排序算法。该算法是采用分治法的一个典型应用。 def MergeSort(arr): if len(arr) <= 1: #当长度为1时,并归结束 return arr mid = len(arr)//2 #对半方式并归 left = MergeSort(arr[:mid]) #递归方法并归左边列表 right = MergeSort(arr...
public class MergeSort { public static void main(String[] args) { //初始化 一个随机的数组 int[] arr = {12, 56, 32, 98, 45, -5, -6, 21, -48, 8}; System.out.println(Arrays.toString(arr)); //打印输出原数组方便后面的调试检查 System.out.println(Arrays.toString(mergeSort(arr)))...
}// 归并排序 O(n*logn)constmergeSort =function(arrayData, compareFn = compare) {letmerge =function(leftArray, rightArray, compareFn) {letresultArray = [];while(leftArray.length>0&& rightArray.length>0) {if(compareFn(leftArray[0], rightArray[0])) { resultArray.push(leftArray.shift());...
冒泡排序(Bubble Sort)是一种简单的排序算法,它通过比较相邻的元素并交换它们的位置来达到排序的目的。具体来说,冒泡排序的基本思想是从左到右依次比较相邻的两个元素,如果前一个元素大于后一个元素,则交换它们的位置。这样一轮比较下来,最大的元素就会被交换到数组的末尾。然后再从左到右进行下一轮比较,直到整个...
