1. Linked list Remove duplicates from Sorted ListGiven a sorted linked list, delete all duplicates such this each element appear only once.For example,Given 1->1->2, return 1->2.Given 1->1->2->3->3, return 1->2->3.Ideas:There are generally two ways to implement a linked list: recursive and non-recursiveRecursive implementations:ListNode*H=Headif(h== NULL)return N
To determine if there are duplicate elements in the list, you can use HashSet,
HashSet can automatically remove repetitive elements;
list
The contains method of a list can determine whether a list contains an element:
AbstractIf we use the C statement in combination with the circle, this is a very simple topic, but if we use C ++ with STL, there will be a very beautiful method.
IntroductionThe values column has five values: 2, 3, 1, 3, and 5. You want to list all elements larger than 2.

This example describes how Python removes repeating elements from a list. Share to everyone for your reference. Specific as follows:
It's easier to remember with built-in set
L1 = [' B ', ' C ', ' d ', ' B ', ' C ', ' A ', ' a ']L2 = List (set (L1)) print L2
There is also a speed difference that is said to be faster and not tested.
L1 = [' B ', ' C ', ' d ', '
