How do we find duplicate elements in an array?..

Answer / Rahul Sagar

To find duplicate elements in an array, you can use various methods. One simple approach is to sort the array and then compare consecutive elements. Another approach is to use a HashSet or HashMap, where each element is added as a key, and if an attempt to add a duplicate causes an error, then that element is a duplicate.
