这道题目其实和基本排序算法中的 merge sort 非常像。我们先来回顾一下 merge sort 的 merge 过程。merge 的过程 可以 是先比较两个数组的头元素，然后将较小的推到最终的数组中，并将其从原数组中出队列。不断循环直到两个数组都为空。具体代码如下：// 将 nums1 和 nums2 合并function merge(nums1, nums...
for(intj =0; j < help.length; j++) { arr[left+j] = help[j]; } returnresult; } publicstaticvoidmain(String[] args) { Code02_SmallSum sort =newCode02_SmallSum(); int[] arr = {5,2,3,4,1}; //int[] arr = {1,2,3,4}; intsmallSum =sort.process(arr,0, arr.length-1)...
1.介绍 归并排序(MergeSort)是利用归并的思想实现的排序方法,该算法采用经典的分治策略(分治法将问题分(divide)成一些小的问题然后递归求解, 而治(conquer)的阶段则将分的阶段得到的各答案“修补”在一起,即分而治之) 2.示意图 说明:可以看到这种结构很像一颗完全二叉树
Merge step Writing the Code for Merge Algorithm A noticeable difference between the merging step we described above and the one we use for merge sort is that we only perform the merge function on consecutive sub-arrays. This is why we only need the array, the first position, the last ind...
void mergeSortedArray(int A[], int m, int B[], int n) { // write your code here int *res=new int[m+n]; for(int i=0;i<m;i++){ res[i]=A[i]; } for(int i=m;i<m+n;i++){ res[i]=B[i-m]; } sort(res,res+m+n);// ...
int[][] intervals){List<int[]> result =newArrayList<>();// Arrays.sort(intervals, Comparator.comparingInt(a -> a[0]));Arrays.sort(intervals,newComparator<int[]>(){publicintcompare(int[] a1,int[] a2){return a1[]- a2[];}});inthead= intervals[][], tail = intervals[][1];for(...
class Solution: def merge_sort(self, nums): # If the array length is less than or equal to 1, return the array (base case for recursion) if len(nums) <= 1: return nums # Find the middle point mid = len(nums) // 2 # Recursively sort the left half left_half = self.merge_sort...
