Given two sorted linked lists consisting of N and M nodes respectively. The task is to merge both of the list (in-place) and return head of the merged list ...

Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. # Definition for singly-linked list ...

If we have two sorted linked list and we want to merge both in a new list without creating new node space then we can use recursive approach for this . This approach takes O(max(m,n)) time complexity ...
