Remove duplicate element from sorted Linked List
Welcome to the daily solving of our PROBLEM OF THE DAY with Devasish Khade. We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Linked List but will also help you build up problem-solving skills.
In this video, we are given a singly linked list consisting of N nodes. The task is to remove duplicates (nodes with duplicate values) from the given list (if exists).
Note: Try not to use extra space. The nodes are arranged in a sorted way.
Example :
Input:
LinkedList: 2->2->4->5
Output: 2 4 5
Explanation: In the given linked list 2 ->2 -> 4-> 5, only 2 occurs more than 1 time. So we need to remove it once.
Give the problem a try before going through the video. All the best!!!
