Solution

The testArray is a two-dimensional array, or an "array of arrays". It contains three elements, each of which is an array:

  1. The first array contains three elements: 1, -2, 3.
  2. The second array is empty, so it contains zero elements.
  3. The third array contains two elements: 5, 6.

So, in total, testArray contains 3 + 0 + 2 = 5 elements.
