The linked list is one of the most important concepts and data structures to learn while preparing for interviews. Having a good grasp of Linked Lists can be a huge plus point in a coding interview.<\/p>\n

Problem Statement<\/h3>\n

In this question, we are given an ArrayList. We have to convert this ArrayList to a LinkedList. <\/p>\n

Problem Statement Understanding<\/h3>\n

Suppose the given ArrayList is [Games, On, A Computer].
\nWe have to convert this ArrayList to LinkedList.
\nThe resultant LinkedList will be:<\/p>\n

\"\"<\/p>\n

An ArrayList is a part of the collection framework and is present in java. util package. It helps us to create dynamic lists. Though it may be a bit slower than arrays but can be of great use where lots of manipulating operations are needed in an array.<\/p>\n

Input :<\/strong> ArrayList – [Games, On, A Computer]<\/p>\n

Output :<\/strong><\/p>\n

Linkedlist
\n\"\"<\/p>\n

Explanation :<\/strong> We can see that the given ArrayList has been converted to a LinkedList.<\/p>\n

This question is not a very complex one. We have to make use of ArrayList traversal to solve it. Let us have a glance at the multiple approaches.<\/p>\n

Approach and Algorithm (Naive Solution)<\/h3>\n

The approach is going to be pretty simple. <\/p>\n

    \n
  • We are going to create a new empty LinkedList. <\/li>\n
  • Then, we will simply traverse through the ArrayList and one by one, insert that element into the LinkedList.<\/li>\n<\/ul>\n
