Remove duplicates from Linkedlist

In this article, we will see program to remove duplicates from Linked list in Python.

Linked list with duplicates -

Linked list after removing duplicates -

Steps -

1. Traverse linkedlist, if a node is equal to next node (i.e duplicate node), link next of node to next next of node.

2. Repeat first step, until all the duplicated nodes are removed or node reaches to null.

Implementation -

def removeDuplicates(head):

while head and head.next:

if head.data==head.next.data:

head.next = head.next.next

else:

head=head.next

return head

Which is best: LeetCode vs HackerEarth ?

Well, all the platforms almost are same except the interface. That's what I think. To conclude the result, let's compare them through the features they offer. Features of Leetcode - Topic - wise questions Comapny-wise questions Weekly contests Interview Preparation section Discuss section Features of HackerEarth Topic-wise problems Monthly contests Discuss section Hiring Contests Hackathons Earlier, when I started coding in my first year. I was fond of HackerEarth. But when I stoped using hackerearth and shifted to Leetcode, I like it more. It depends upon how much comfortable you are with the interface. But, it can't be denied that Leetcode offer more than HackerEarth. But for the coders who love hackathons, HackerEarth is best for them and for the people looking out for job opportunities.

Top Questions asked by Facebook

Facebook is the dream company of almost every software engineer. If you are doing interview preparation, you can't skip the must do coding questions for Facebook. Facebook is the product-based company and tests the candidate on data structures and algorithms, and logical questions. The coding level is a bit tough, but you can do it with your hard work. Below is the list of coding questions you must prepare before sitting for Facebook.
