How do I handle duplicates when sorting a list?

How do I handle duplicates when sorting a list?

You can handle duplicates in sorting by using a set to remove them before sorting, or by using a sorting algorithm that accounts for duplicates.

Can you show me an example in Python?

Sure! You can use this code:

my_list = [3, 1, 2, 2, 3]
unique_sorted_list = sorted(set(my_list))
print(unique_sorted_list)  # Output: [1, 2, 3]

What if I want to keep the duplicates but still sort the list?

If you want to keep duplicates, simply sort the list directly:

my_list = [3, 1, 2, 2, 3]
sorted_list = sorted(my_list)
print(sorted_list)  # Output: [1, 2, 2, 3, 3]

Are there any sorting algorithms that handle duplicates better?

Yes, algorithms like Merge Sort and Quick Sort can handle duplicates efficiently, maintaining their relative order.
