Question 23: List Elements

Collecting Snacks for a School Picnic

1. View the Current Snacks

   • Start with a list of snacks the students have already brought: apple, banana, carrot sticks, sandwich, juice box.

2. Add More Snacks

   • Decide to add more snacks to the list, such as granola bar, cookies, and water bottle.

3. Access Specific Snacks

   • Show a specific snack from the list (for example, the 3rd snack) to check what’s available.

4. Remove Snacks

   • Remove the last snack added because it is no longer needed.

   • Remove another snack from the end to simplify the sharing plan.

   • Remove a specific snack from the middle of the list if it’s too messy to carry.

5. Update Snacks

   • Change one of the snacks in the list (for example, replace carrot sticks with grapes) because the students prefer it.
