Return the head of the merged linked list. Problem Statement: Given the heads of two linked lists, list1 and list2, where each linked list has its elements sorted in non-decreasing order, merge them into a single sorted linked list and return the head of the merged linked list. The goal is to preserve the non-decreasing order of elements and return the head of the newly merged list.

Aug 30, 2025 · [Efficient Approach] Using Iterative Merge - O (n+m) Time and O (1) Space [Naive Approach] By Using Array - O ( (n+m) × log (n+m)) Time and O (n+m) Space The idea is to use an array to store all the node data from both linked lists, sort the array, and then construct the resultant sorted linked list from the array elements. Example: 12 You are given an array of k linked-lists lists, each linked-list is sorted in ascending order. It looks simple at first, but it tests how well you can think about pointer manipulation and how efficiently you can take advantage of already-sorted inputs. tdm xpm wcy wcv iua wjh frh cta mic jtk ome jeu yub rvy dya
