Here are some other ways to access array objects in Ruby.
To access the elements from the end of the list, we can use negative indices.
For the array,
arr = [9, 5, 1, 2, 3, 4, 0, -1]
> arr[-1] => -1
- The first element of the array can be accessed using
> arr.first => 9
- The last element of the array can be accessed using
> arr.last => -1
- The first
n
elements of the array can be accessed using
arr.take(3) => [9, 5, 1]
- Everything but the first
n
elements of the array can be accessed using
arr.drop(3) => [2, 3, 4, 0, -1]
In this challenge, you have to use the syntax as explained above and complete the functions accordingly.
