Solution

In the given question, we are asked to identify which arrays are of perfect size. An array is said to be of perfect size when it doesn't contain any null values and all its allocated memory is being used.

Let's analyze each array:

  1. aces array: It has 4 elements - "black", "gray", "white", "purple". There are no null values and all its allocated memory is being used. So, aces is a perfect size array.

  2. stripes array: It has 5 elements - "blue", "pink", null, "pink", "blue". Here, one element is null. So, even though all its allocated memory is being used, it's not considered a perfect size array because it contains a null value.

  3. flags array: It has 4 elements - "yellow", null, "purple", "black". Here, one element is null. So, even though all its allocated memory is being used, it's not considered a perfect size array because it contains a null value.

So, the correct answer is aces array. It's the only perfect size array among the given arrays.
