148. Sort List Sort a linked list in O(n log n) time using constant space complexity. Example 1: Input: 4->2->1->3 Output: 1->2->3->4 Example 2: Input: -1->5->3->4->0 Output: -1->0->3->4->5 思路: 题目意思很明确,给一个链表排序,排序的方式有很多,这里写一下归...
【Leetcode】Insertion Sort List https://leetcode.com/problems/insertion-sort-list/ 题目: Sort a linked list using insertion sort. 思路: 头插法。用头结点可以简化插入链表时候的操作,因为要考虑插入链表中间和表头两种情况,插入表头时,head就要更新,还要判断pre指针是否为空...

python 两种排序方法 sort() sorted() 2019-12-12 15:31 −python中有两种排序方法,list内置sort()方法或者python内置的全局sorted()方法 区别为: sort()方法对list排序会修改list本身,不会返回新list。sort()只能对list进行排序。 sorted()方法会返回新的list,保留原来的list。sorted ... ...
python中sort和sorted的另类用法 2019-12-25 08:59 −排序应该是处理list列表经常用到的方法,常用的就是sort和sorted。 一、两者的差异 1、list.sort()是list是内建方法,使用sort会直接改变原列表的顺序,而sorted(list)只会返回一个已排好序的列表,如下: 1 >>> a... ...
