How Deep

How Deep

English RU UK

You are given a tuple that consists of integers and other tuples, which in turn can also contain tuples.

Your task is to find out how deep this structure is or how deep the nesting of these tuples is.

For example, in the (1, 2, 3) tuple the depth of nesting is 1. And in the (1, 2, (3,)) tuple the depth of nesting is 2, since one of the elements of the first tuple is also a tuple. And in the (1, 2, (3, (4,))) tuple the depth of nesting is 3, since one of the elements of the first tuple is a tuple, but since inside it contains another tuple, it increases the depth by one, so the nesting depth turns out to be 3.

It’s important to note that an empty tuple also increases the depth of the structure, that is, () - indicates the nesting depth 1, ((),) - indicates the nesting depth 2.

Input: Tuple of tuples of tuples...of integers.

Output: Integer.


assert how_deep((1, 2, 3)) == 1
assert how_deep((1, 2, (3,))) == 2
assert how_deep((1, 2, (3, (4,)))) == 3
assert how_deep(()) == 1

Precondition: Given iterables have to be well founded.

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon
