Get One Dimensional Array Using Slice and Only Positive Indexes Get One Dimensional Array Using Slice and Only Positive Indexes

Let's examine the syntax of slicing: array[start:end:step], where:

  • start is the index from which the slicing begins;
  • end is the index at which the slicing concludes (note that this index is not included);
  • step is the parameter that specifies the intervals between the indices.

Tarefa

Consider the following array: [11, 5, 87, 1, 44, 11, 6, 0, -5].
You need to obtain the following array: [87, 11, -5].
Use a slice with ONLY NON-NEGATIVE start, end, and step values.
