Can someone point out where the list resizes the third time (in the question below)
Question: How many times will the list need to resize while the following code runs?
List favoriteThings = new List();
favoriteThings.Add("sunshine");
favoriteThings.Add("ice cream");
favoriteThings.Add("babies laughing");
favoriteThings.Add("chocolate chip cookies");
favoriteThings.Add("Star Trek");
favoriteThings.Add("bean bag chairs");
favoriteThings.Add("apples");
favoriteThings.Add("snow");
favoriteThings.Add("mountain streams");
favoriteThings.Add("trees");
Answer: 3 times

Justin Horner
Treehouse Guest TeacherHello, Carel
The array is resized in this order:
favoriteThings.Add("sunshine");
The first time we add an item, the list is resized to a capacity of 4.
favoriteThings.Add("Star Trek");
Adding a 5th item causes a resize so that the capacity doubles to 8.
favoriteThings.Add("mountain streams");
The final resize happens because we've now asked the list to add a 9th item when it only has a capacity of 8. The resize results in a capacity of 16.
I hope this helps.
