1. Find Duplicates In Array
Easy
15m average time
90% success
0/40
Asked in companies
You are given an array/list 'ARR' consisting of N integers, which contains elements only in the range 0 to N - 1. Some of the elements may be repeated in 'ARR'. Your task is to find all such duplicate elements.
Note:
1. All the elements are in the range 0 to N - 1.
2. The elements may not be in sorted order.
3. You can return the duplicate elements in any order.
4. If there are no duplicates present then return an empty array.
Problem approach
I used Hashset to solve this problem. Java was my primary language to code and I prefered to solve in it. Keep on adding elements from array in Hashset and the element that returns false means it's already present in hashset and is hence duplicate. Print such element.
