Code to print duplicate numbers in a list.

• Iterate through the list and keep track of the count of each number using a dictionary.

• Print the numbers that have a count greater than 1.

1. A= [1, 2, 3, 4, 2, 7, 8, 8, 3];

3. print("Duplicate elements are: ");

4. #Searches for duplicate element

5. for i in range(0, len(A)):

6. for j in range(i+1, len(A)):

7. if(A[i] == A[j]):

8. print(A[j]);
