NumPy in a Nutshell

## 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.

# Task

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.

Everything was clear?
