Dec 14, 2023 · Given an array arr of N elements, the task is to find the length of the smallest subarray of the given array that contains at least one duplicate element. A subarray is formed from consecutive elements of an array.
Find All Duplicates in an Array - Given an integer array nums of length n where all the integers of nums are in the range [1, n] and each integer appears once or twice, return an array of all the integers that appears twice.
Given an array arr of size n which contains elements in range from 0 to n-1, you need to find all the elements occurring more than once in the given array. Return the answer in ascending order. If no such element is found, return list containing

Feb 14, 2017 · Find All Duplicates in an Array. Description. Given an integer array nums of length n where all the integers of nums are in the range [1, n] and each integer appears once or twice, return an array of all the integers that appears twice. You must write an algorithm that runs in O(n) time and uses only constant extra space. Example 1:
Find All Duplicates in an Array. Medium Array Hash Table. Leetcode Link. Problem Description. This problem asks us to find all the numbers that appear twice in an array nums, where the array has a length n, and all elements in the array are within the range [1, n]. The elements in the array can either appear once or twice.
The most basic way to find duplicate elements in an array is by using a nested for loops. For each element in the array, check if it is present in the rest of the array or not, if it is present, then increment the count of duplicates by 1.
Given an integer array, nums, of length n n n, where all the integers of nums are in the range [1, n] [1, n] [1, n] and each integer appears once or twice, return an array of all the integers that appear twice.
Mar 27, 2024 · The naive approach to Find All Duplicates in an Array will be to take each element and to find whether any second occurrence of that element is present in the entire array or not. If any second occurrence is present, then we need to display it in the answer array.
May 7, 2024 · Given an array of n elements containing elements from 0 to n-1, with any of these numbers appearing any number of times, find these repeating numbers in O(n) and using only constant memory space. Example: Input: n = 7 , array = {1, 2, 3, 1, 3, 6, 6} Output: 1, 3 and 6. Explanation: Duplicate element in the array are 1 , 3 and 6 Input: n = 6, array
