How do I merge two sorted linked lists?

How do I merge two sorted linked lists?

Write a SortedMerge() function that takes two lists, each of which is sorted in increasing order, and merges the two together into one list which is in increasing order. SortedMerge() should return the new list. The new list should be made by splicing together the nodes of the first two lists.

How do you sort a linked list in C?

Algorithm

1. Create a class Node which has two attributes: data and next.
2. Create another class SortList which has two attributes: head and tail.
3. addNode() will add a new node to the list:
4. sortList() will sort the nodes of the list in ascending order.
5. display() will display the nodes present in the list:

Why is merge sort preferred for linked list?

Why is Merge Sort preferred for Linked Lists? In the case of linked lists, the nodes may not be present at adjacent memory locations, therefore Merge Sort is used. To access ith index in a linked list, we have to travel each and every node from the head to ith node as we don’t have a continuous block of memory.

How do you add two linked lists in C++?

We just need to follow some very simple steps and the steps to join two lists (say ‘a’ and ‘b’) are as follows: Traverse over the linked list ‘a’ until the element next to the node is not NULL. If the element next to the current element is NULL (a->next == NULL) then change the element next to it to ‘b’ (a->next = b).

Is merge sort or quick sort suitable for sorting linked list justify?

Merge sort is faster in these situations because it reads the items sequentially, typically making log2(N) passes over the data. There is much less I/O involved, and much less time spent following links in a linked list. Quicksort is fast when the data fits into memory and can be addressed directly.

How will you merge elements in a sequence?

Python String join() method is a string method and returns a string in which the elements of the sequence have been joined by the str separator.

1. Syntax:
2. Parameters:
3. The join() method takes iterable – objects capable of returning their members one at a time.
4. Return Value:
5. Type Error:

How to merge two sorted linked lists using C++?

Merge two sorted linked lists using C++. Given 2 sorted singly linked list. Write a function to merge given two sorted linked lists 1. Traverse both lists 1.1. If list1->data < list2->data 1.1.1 Add list1->data to new list and increment list1 pointer 1.2 If list2->data < list1->data 1.2.1 Add list2->data to new list and increment list2 pointer 2.

How do you sort a list of linked lists?

The new list should be made by splicing together the nodes of the first two lists. For example if the first linked list a is 5->10->15 and the other linked list b is 2->3->20, then SortedMerge () should return a pointer to the head node of the merged list 2->3->5->10->15->20.

How does sortedmerge() work in SQL?

For example if the first linked list a is 5->10->15 and the other linked list b is 2->3->20, then SortedMerge () should return a pointer to the head node of the merged list 2->3->5->10->15->20.

How to find the smaller node among two linked lists?

There are different discussed different solutions in post below. Approach: The recursive solution can be formed, given the linked lists are sorted. Compare the head of both linked lists. Find the smaller node among the two head nodes. The current element will be the smaller node among two head nodes.
