This post will discuss how to find the duplicate elements in a list in C#... The idea is to use the Enumerable.GroupBy() method to group the elements based on their value, then filter out the groups that appear more than once, and retrieve the duplicates
Finding duplicate array elements. Latest version: 1.0.0, last published: 6 months ago. Start using find-duplicate-array-elements in your project by running `npm i find-duplicate-array-elements`. There are no other projects in the npm registry using find-
Given an array of integers, 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements that appear twice in this array. Could you do it without extra space and in O(n) runtime? Example: Input: [4,3,2,7,8,2,3,1] Output: [2...
Write a Python program to find the first duplicate element in a given array of integers. Return -1 if there are no such elements.Sample Solution:Python Code :def find_first_duplicate(nums): num_set = set() no_duplicate = -1 for i in range(len(nums)): if nums[i] in num_set: re...
In Java 8 Stream, filter withSet.Add()is the fastest algorithm to find duplicate elements, because it loops only one time. Set<T> items =newHashSet<>();returnlist.stream() .filter(n -> !items.add(n)) .collect(Collectors.toSet());Copy ...

[i1, i2] = findduplicates(A) finds the linear indices of duplicates in input A. The accepted input arguments are the same as accepted by the unique function. The first output, i1, contains the linear indices of the first duplicate elements into A that correspond to the duplicates indexed...
In this article, we are going to see how to find nearest greatest neighbours of each element in an array in minimum time complexity? Submitted by Radib Kar, on November 16, 2018 Problem statement:Given an array of elements, find the nearest (on the right) greatest element ofeach elemen...
