Example 1: java remove duplicates
import java.util.*;
public class RemoveDuplicatesFromArrayList {
public static void main(String[] args) {
List<Integer> numbers = Arrays.asList(1,2,2,2,3,5);

Set<Integer> hashSet = new LinkedHashSet(numbers);
ArrayList<Integer> removedDuplicates = new ArrayList(hashSet);
System.out.println(removedDuplicates);
}
}
Example 2: remove duplicates from sorted array
def remove_duplicates(nums: [int]) -> int:
cnt = 1
