Removing duplicates from a sorted array is a common problem asked in many coding interviews and programming challenges. This can be approached using different methods. In this article, we'll discuss two approaches to remove duplicates from a sorted a...
In the world of algorithms and data structures, efficient solutions often rely on clever techniques to manipulate data. One such technique, the "two pointers" approach, is particularly useful for solving a variety of problems. While traditionally ass...
Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place such that each unique element appears only once. The relative order of the elements should be kept the same. Then return the number of unique elements in nums....
Greetings, fellow coders and innovators!👋 Introduction Once in a coding challenge, I faced duplicate data issues, like repeated candies in a jar. Determined to solve it, I explored JavaScript's Set and mastered "Removing Duplicates and Creating Dist...
Understanding the question(challenge) The first process of solving this challenge is understanding the question. Understanding the question gave me basis for me to start trials. Question: Given an integer array nums sorted in non-decreasing order, re...
Disclaimer: Most of the content for problem statement is taken from algodaily.com Problem Statement Given an array, return another array with just the ordered unique elements from the given array. In other words, you're removing any duplicates. Note:...
In today's posts, I will show you two methods on how to remove duplicates from an array. In our first example, we will remove duplicates from our array using a Set. The Set object lets you store unique values of any type, whether primitive values or ...
let arr = [2, 1, 3, 1, 7, 1, 7, 9, 3]; function removeDuplicates(arr) { let obj = {}; let arrWithNoDuplicates = []; for (let i = 0; i < arr.length; i++) { obj[arr[i]] = true; } for (let key in obj) { arrWithNoDup...
var users = [ { name: 'Rahul', email: 'test1@test.com' }, { name: 'Rajeev', email: 'test2@test.com' }, { name: 'Revanth', email: 'test2@test.com' } ]; let emailIds = users.map( (item) => { return item.email; }) let...
