题解: 这道题是说让B merge到 A 里面。 先复习下原本我们在MergeSort里面怎么利用一个新建的数量来merge two array: 代码如下: 1publicint[] mergeTwoList(int[] A,int[] B) { 2int[] C =newint[A.length + B.length]; 3intk = 0; 4inti = 0; 5intj = 0; 6while(i < A.length && j...
public static void main(String[] args) { int[] array = {3, 44, 38, 5, 47, 15, 36, 26, 27, 2, 46, 4, 19, 50, 48}; // 只需要修改成对应的方法名就可以了 mergeSort(array); System.out.println(Arrays.toString(array)); } /** * Description: 归并排序 * * @param array * ...
public class TestMergeSort { public static void sort(int[] arr){ //先重载一个给整个数组排序的方法 不用手动输入low=0 high=length-1 方便使用更易懂 sort(arr, 0, arr.length-1);//最高位是length-1 } public static void sort(int[] arr,int low,int high){ if (low<high){ //当low=hi...
问简单的Java mergeSort实现EN// Creating resulting array int[] outputArr = new int[n]; /...
MergeSort算法是一种常见的排序算法,它采用分治的思想将一个大问题分解为多个小问题,并通过合并已排序的子数组来解决原始问题。在Java中,MergeSort算法的实现可能会遇到IndexOutOfBoundsException异常。 IndexOutOfBoundsException是Java中的一个运行时异常,表示索引超出范围。在MergeSort算法中,当对数组进行划分并递归...
这是mergesort的java实现。刚开始对sort进行一些了解。 所以参照网上的一些经验和分享,自己写了写。并整合了下来。 package sorting; public class MyMergeSort { private int[] array; private int[] tempMergArr; private int length; public static void main(String a[]){ ...
void mergesort(int a[], int first, int last, int temp[]) { if (first < last) { int mid = (first + last) / 2; mergesort(a, first, mid, temp); //左边有序 mergesort(a, mid + 1, last, temp); //右边有序 mergearray(a, first, mid, last, temp); //再将二个有序数列合...
Copy remaining elements of second array to main subarray This step would have been needed if the size of M was greater than L. At the end of the merge function, the subarray A[p..r] is sorted. Merge Sort Code in Python, Java, and C/C++ Python Java C C++ # MergeSort in Python...
Given an integer array, sort it in ascending order. Use quick sort, merge sort, heap sort or any O(nlogn) algorithm.
