Managing collections of data with lists and arrays can be tricky. Let’s break down some challenges you might face:

1. Complexity:

   • Arrays have a fixed size. This means once you set them up, you can't easily change how many items they hold.
   • Lists can grow when you need more space. But keeping track of how much memory they use can be inefficient or messy.

2. Indexing Issues:

   • When you work with indexes, it can get confusing.
   • If you forget that indexing starts at zero, you might make mistakes, like getting the wrong item or missing one.

3. Data Type Limitations:

   • Arrays are best for holding the same type of data.
   • If you try to mix different types, it can lead to problems.

Solutions:

• Use linked lists. They are more flexible for changes.
• Use error-checking to make sure your indexes are correct.
• Consider using dictionaries. They let you mix different types of data without complications.
