Please note that we can use HashSet to remove duplicate elements from a List, but it is an unordered collection and will not honour the order of the elements in the List. ALinkedHashSet, on the other hand, is an ordered collection of unique elements. We can safely use it to remove du...
2. UsingStream.distinct()to Remove Duplicate Elements and Get a New List We can use the Java 8Stream.distinct()method which returns a stream consisting of the distinct elements compared by the object’sequals()method. Finally, collect all district elements asListusingCollectors.toList(). ArrayL...
This tutorial will introduce the methods to remove duplicate elements from a list in C#. ADVERTISEMENT TheHashSetclassis used to create a set in C#. A set is a well-known, unordered collection of distinct objects, which means that a set’s elements are unordered and do not repeat themselves...
In this example, we have anArrayList that contain duplicate elements. We are iterating this ArrayList and adding the elements of it to a new list. We have placed a code inside iterating loop in such a way thatif the element is already present in the new list, skip adding that element....
In C++ STL, to remove consecutive duplicate elements, we use a library function of "list" header, that is unique(), this function removes all consecutive duplicate elements from the list (similar to other containers also). And we get the list without consecutive duplicate elements....

how to Remove duplicate items from list and leave only one items from every duplicated: ex : a = [1,1,1,2,2,2,3,3,3] result = [1,2,3]
Removing Duplicate Elements from Array We need to remove duplicate elements from array so that each element only appears once (all the values in the array should become unique). Example Input: [1,2,2,3,4,4,4,5,5] Output: [1,2,3,4,5] Explanation The frequency of each element is sh...
This solution is highly functional and relatively easy to understand. However, the performance of this algorithm degrades significantly as the number of duplicate elements grows. A reviewer for a coding job at Google or Facebook would not be particularly fond of this algorithm. ...
In Python, how can I efficiently remove duplicates from a list while maintaining the original order of elements? I have a list of integers, and I want to remove duplicat
