Given 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.The idea of solving a problem is to traverse the list, if the elements of the 2 nodes are equal, delete the latter one, otherwise it will be shifted. It is important to note that you do not directly manipulate the head or the head will change

As a seoer, we are inevitably confronted with a wide variety of users when it comes to different kinds of optimizations, and it does take a lot of skill to communicate with these people. If you do not talk, you will lose the user, or the price is depressed, no profits. As the saying goes, "Our client is God." But to tell the truth, we will inevitably encounter some bad temper or a little bit of seo "God", but no way, since we chose the road of SEO, we need to first put their own mentality. It's

-----------Incoming array------returns listIn SQL we can pass in a list or an array and return a list.This uses the in of SQL and uses the traversal in SQL.When we want to pass the string parameter to Mapper.xml, we need to set it in SQLParametertype= "String"Also make sure that the parameter names in the Impl and the names in SQL are identical.As follows:@Overridepublic user Findbyue (String userId) throws Exception{return (user) Dao.findforobject ("

Question: In a sorted list, how to delete duplicate nodes. For example, the following figure: The detailed implementation code is as follows: Delete duplicate node void deleteduplication (listnode** phead) {if (Phead = = NULL | | *phead = NULL) return; listnode* Pprenode = NULL; listnode* pnode = *phead; while (Pnode!= NULL) {ListNode *pnext = pnode->m_pnext; BOOL Needdelete = false; if (pnext!= NULL pnext->m_nvalue
