Traversal Patterns

1. Linear Traversal: Iterate through the list sequentially.

   • Example: for item in my_list: checks each element.

2. Index-Based Traversal: Access elements using indices.

   • Example: for i in range(len(my_list)): allows modifying elements during traversal.

3. Nested Traversal: Traverse lists within lists.

   • Example: for sublist in my_list: for item in sublist: handles 2D lists.

4. Efficiency Considerations: Discuss when to use each pattern based on the problem.
