[ ASSIGNMENT: ] Next bigger number with the same digits

Question

TASK :
You have to create a function that takes a positive integer number and returns the next bigger number formed by the same digits :

For Example ::

next_bigger(12) --> return 21
next_bigger(513) --> return 531
next_bigger(2017) --> return 2071

If no bigger number can be composed using those digits, return -1 :

next_bigger(9) --> return -1
next_bigger(111) --> return -1
next_bigger(531) --> return -1

quite new to oop en inheritance, so probably it could be optimized quite a lot

I didn't notice about next bigger, so I update my code from next smaller, to have both

It use slices, so there is not limit like permutations about digits quantity
