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...
In this article, we are going to check how we can remove duplicate elements from an array in C# using different approaches. What are Duplicate Elements in an Array? The elements which exist more than once in a given array are duplicate elements. In this problem, we are given an array, ...

If we remove all the duplicate elements from theSet, it will contain only the unique elements. distinctElementsSet.removeAll(Arrays.asList(duplicateElementsArray));Integer[]uniqueElementsArray=distinctElementsSet.toArray(Integer[]::new);System.out.println("Unique elements in the array : "+Arrays.t...
An unsorted array arr consisting of n elements is given, write a program to remove all the duplicate elements from the array. Problem Note All the elements in the resultant array must be unique. The elements of the resultant array can be in any order. Example 1 Input: arr[] = ...

As observed, the duplicate elements from the unsorted arrays are also removed in the same manner as sorted arrays. But here, one additional method is used to sort the unsorted array. It is to be noted that one should check whether the array is sorted or not and then proceed with the nex...

For example, Given sorted array nums = [1,1,1,2,2,3], Your function should return length = 5, with the first five elements of nums being 1, 1, 2, 2 and 3. It doesn’t matter what you leave beyond the new length. 【解释】 作为删除数组中重复元素的进化版,要求最后目标数组中最多...
