HashSet is an unordered collection that uses hashing to store and retrieve elements efficiently.

• HashSet internally uses a HashMap to store its elements.

• Each element is stored as a key in the HashMap with a fixed value.

• When adding an element, its hash code is calculated and used to determine the bucket in the HashMap where it will be stored.

• If multiple elements have the same hash code, they are stored in the same bucket...read more

Use a hash set to keep track of unique elements while iterating through the array.

• Create a hash set to store unique elements.

• Iterate through the array and check if each element is already in the hash set.

• If the element is not in the hash set, add it to the hash set.

• If the element is already in the hash set, it is a duplicate entry.
