Prompt

Write a program that will take a string of digits and give you all the possible consecutive slices of length n in that string.

Raise an error if n is larger than the length of the string.
Examples

For example, the string "01234" has the following 2-digit slices:

[0, 1], [1, 2], [2, 3], [3, 4]

The same string has the following 4-digit slices:

[0, 1, 2, 3], [1, 2, 3, 4]
