Need help removing duplicates from an array using the method

Question

Hello everyone,

I've been working on a coding problem that involves removing duplicates from an array, and I came across this tutorial on Remove Duplicates from Array. It provides a method that seems promising, but I'm having trouble implementing it correctly.

I followed the steps mentioned in the tutorial, but my code doesn't seem to be removing all the duplicates as expected. I'm not sure if I'm missing something or if there's an error in my implementation.

Here's the code snippet I used:

```python
# My code
# Insert code here

```

I would really appreciate it if someone could take a look at my code and provide some guidance. If you have successfully solved a similar problem or have any suggestions for alternative approaches, I would love to hear them as well.

Also, if you've used the method described in the tutorial and it worked for you, please let me know. It would help me identify if the issue lies in my code or elsewhere.

Thank you in advance for your assistance and insights.
