If you like to have a function where you can send your lists, and get them back without duplicates, you can create a function and insert the code from the example above. Example defmy_function(x): returnlist(dict.fromkeys(x)) mylist =my_function(["a","b","a","c","c"]) ...

Python'sdictclass has afromkeysclass methodwhich accepts aniterableand makes a new dictionary where the keys are the items from the given iterable. Since dictionaries can't have duplicate keys, this also de-duplicates the given items! Dictionaries also maintain the order of their items (as of ...

Remove Duplicates from Sorted List是删除链表重复节点,但是要留下一个重复的节点。 这题因为第一个节点也可能重复,所以需要另外新建一个节点,指向该链表。 遍历链表,当下一个节点和当前节点不同,将当前节点加到链表中(将链表的next指向该节点)。当下一个节点和当前节点相等,则继续遍历,直到不相等的那一个,然后...
1. 原始题目 Given a sorted linked list, delete all duplicates such that each element appear onlyonce. Example 1: Input: 1->1->2 Output: 1->2 Example 2: Input: 1->1->2->3->3 Output: 1->2->3 2. 题目理解 给定一个排序链表,删除所有重复的元素,使得每个元素只出现一次。
