代码(Python3) classSolution:defmerge(self,nums1:List[int],m:int,nums2:List[int],n:int)->None:"""Do not return anything, modify nums1 in-place instead."""# i/j 分别表示 nums1/nums2 中还未使用的最大数的下标i,j=m-1,n-1# k 表示 nums1 中下一个该填充的位置。k:int=m+n-1#...
You are given two integer arrays nums1 and nums2, sorted innon-decreasing order, and two integers m and n, representing the number of elements in nums1 and nums2 respectively. Mergenums1 and nums2 into a single array sorted innon-decreasing order. The final sorted array should ...
Given two sorted integer arraysnums1andnums2, mergenums2intonums1as one sorted array. Note: The number of elements initialized innums1andnums2aremandnrespectively. You may assume thatnums1has enough space (size that is greater or equal tom+n) to hold additional elements fromnums2. Example: ...
思路一、很简单,利用python的特性,将nums2的前n项,给nums1的m项之后做延伸,然后对nums1做sort()即可,代码示例为 :merge2; 思路二、从后往前遍历,取三个游标,其中两个游标分别对应nums1和nums2,因为nums1的长度不限,最终合并的数组依然在nums1中,所以设置一个新的合并之后的nums1的游标,长度设置为 m+n-1...

Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 合并两个有序链表 /** * Definition for singly-linked list. * struct ListNode { * int val; ...
After that, the merge function comes into play and combines the sorted arrays into larger arrays until the whole array is merged. MergeSort(A, p, r): if p > r return q = (p+r)/2 mergeSort(A, p, q) mergeSort(A, q+1, r) merge(A, p, q, r) To sort an entire array, we...
合并排序算法减少了两个数字集合中的原始数组,并在排序2集合(1集合x1集合)之后、2x2、3x3等之后放置较低的数组。最后对数组进行排序。问题是:如果第二个mergeSort()调用mergeSort()和merge时没有将输出分配给数组,那么这个算法(在Java中的实现)如何排序数组呢?我称该算法为:int[] sorted_array = < 浏览7提...
用一个大小为K的最小堆(用优先队列+自定义降序实现)(优先队列就是大顶堆,队头元素最大,自定义为降序后,就变成小顶堆,队头元素最小),先把K个链表的头结点放入堆中,每次取堆顶元素,然后将堆顶元素所在链表的下一个结点加入堆中。 代码语言:javascript ...
Looking to the literature on sorting almost-sorted data, the best-known current technique is Timsort, which is the system sort in Python, and is used to sort arrays of non-primitive type in Java SE 7, on the Android platform, and in GNU Octave [8]. Timsort has a heavily optimized ...
