Challenge: Union and Intersection of Linked Lists
Try to solve the Union and Intersection of Linked Lists problem.
We'll cover the following
Statement
Given the heads of two linked lists, head1
and head2
, as inputs. Implement the union and intersection functions for the linked lists. The order of elements in the output lists doesn’t matter.
Here’s how you will implement the functions:
: This function will take two linked lists as input and return a new linked list containing all the unique elements.Union This combines elements from two sets, removing duplicates, to form a new set with all unique elements from both original sets. : This function will take two linked lists as input and return all the common elements between them as a new linked list.Intersection This identifies and collects elements that are common to both sets, excluding all others, to create a set of shared elements.
Constraints:
Let n
be the number of nodes in both linked lists:
