## LeetCode 21 合并链表 ## 引用官方代码,定义结点类 class ListNode: def __init__(self, x): self.val = x self.next = None 将数组转换为链表,也可以理解为链表的创建(官网不给出): ## 将给出的数组,转换为链表 def linkedlist(list): head = ListNode(list[0]) ## 列表的第一个元素。这里...
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 < B.length) { 7if(A[i] < B[j]) ...

Leetcode每日一题:88.merge-sorted-array(合并两个有序数组),思路:最容易想到的就是归并排序的归并策略了,时间复杂度O(m+n),空间复杂度O(n);但是官网给出了另一个难以想到的妙招,就是反向归并,因为nums1最后面的n个元素是空的,所以从后端开始归并,每次选择较大的放

之前做过两个有序链表的排序插入Leetcode21 Merge Two Sorted Lists。当时有暴力循环迭代的方法,还有递归的方法。每次加入一个元素,然后对剩下的元素继续调用函数进行排序插入。 这次是k个,感觉总体思路不会差太多。如果我们想要继续使用递归的方法,对于参数的处理就不会合并两个链表一样简单。因为当时只有两个参数,...
