Orting array by repeatedly reversing - how to write code?

Hi,

I am following some tutorials and online training courses and I encountered task I don't really understand. I would be happy if someone can help me write the code. I usually code in Python, but any language will help as long as I understand the logic of it!

Thank you very much!

The logical problem:

Quote:

def get_reversals_to_sort(self, a)
""""
You need to sort an array of integers by repeatedly reversing
the order of the first several elements of it.

For example, to sort [11,14,12,13], you need to reverse the order of the
first two (2)
elements and get [14,11,12,13], then reverse the order of the first four (4)
elements
and get [13,12,11,14] and then reverse the order of the first three (3)
elements.


The method should return array of integers corresponding to the required
reversals.
For the previous example, given an array [11,14,12,13]
the method should return a array with integers [2,4,3].

:param a: list of numbers
:returns: list of numbers
"""
pass

I am sorry, I have not tried anything so far, because I don't understand how it works...:/
