python merge two lists

Merge two sorted linked lists and return it as a new list. The new list shoshould be made by splicing together the nodes of the first two lists. Example: Input: 1->2->4, 1->3->4Output: 1->1->2->3->4->4 Idea: Compare the values of two linked lists one by one. Smaller values are stored in the new linked list, and so on.

Title Description: Merge sorted linked lists and return it as a new list. The new list should is made by splicing together the nodes of the first of the lists.In fact, the topic is very simple to understand, that is, two orderly linked lists into a new linked list.1 defmergetwolists (self, L1, L2):2 ifL1 = =None:3 returnL24 elifL2 = =N

Idea: Put the head of each list in the smallest heap, take the first heap at a time, and then take the next node out into the heap.1 classcmp{2 Public:3 BOOL operator() (listnode* l1,listnode*L2)4 {5 returnL1->val>l2->Val;6 }7 };8 classSolution {9 Public:Tenlistnode* mergeklists (vectorlists) { Onelistnode* head,*ptr1,*ptr2; APriority_queueminheap; - for(intI=0; I) - if(lists[i]!=NULL) the Minheap.push (

02-linear structure 1 merge the sequence of two ordered linked lists, 02-linear A function is required to merge the incremental integer sequence represented by two linked lists into a non-decreasing integer sequence. This question is more basic and mainly describes the basic operations of the linked list in C language.

Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity.For this problem, it was not known in Java that there is a well-packaged data structure-the priority queue. The priority queue is actually the equivalent of a maximum or minimum heap, which is able to sort the elements in the queue according to the implementation method specified.This will be done, the elements

Merge two sorted linked lists and return it as a new list. The new list shoshould be made by splicing together the nodes of the first two lists.
