Working with lists or arrays can be tricky sometimes.

Here’s what you need to know:

• Adding items: Sometimes, you have to make the list bigger, and that can be tough.
• Removing items: If you’re not careful, you might create empty spots or lose important information.
• Modifying items: Figuring out the right spot to change something can be confusing.

But don't worry! You can overcome these challenges by practicing and learning how to use the different methods of data structures.
