What is a partition? Define partition..
Examples assumed that partition is something the user should be aware of?

https://en.wikipedia.org/wiki/Pascal%27s_triangle
The sum of the elements of row 2 ** n.

The solution is 2 ** n -1.
From a mathematical point of view, why -1?

I think the sentence in the description should read:

Prepare a code that given the number of digits n, may output the amount of palindromes of length equals to n and the total amount of palindromes below or equal to 10ⁿ.

python new test frameworks

Description markdown is broken when Java is selected.

In the description, under "Examples", the brackets in proc_arrInt(arr1) ------> [21, 2, [9, [36]] are mismatched (3 opening, 2 closing).

the tests depend on OrderedDict being imported by the user at the top level

from solution import *

should be:

from collections import OrderedDict
from solution import Array

This kata have several issues:

• sometimes uses << < < or >> > > with no added value, why adding to 2 different operators???
• oblies to return an array in the order the numbers appeared, limiting some types of solutions, and gives no explanation for it, it is not specified in the descripion, and same as before, it adds no value to the kata
• if the kata oblies to return all possible solutions, why if only 1 solutions exist, needs to be returned a an [] and not the same than any other case, an nested array, like: [ [] ]
• relies on depracated Test module

otherways great kata, super fun, should be kyu 4 at least... this can't be the same as splitting a url.

EDIT: I forked the kata, please approve, I speeded up the solution and make the changes aformention in the top section. Fork bellow:

Python random tests say "...matrices up to 20 rows or 20 columns..." although only up to 9 is tested (as stated in the description).

Random tests in Python don't satisfy the requirement for the limit.

For example:
limit = 6,
numbers = [9215, 6629, 7139],
base list = [9, 6, 2, 1, 5] - this is smaller than limit=6.

Go random tests are broken:

Random tests
With arr = [0 0 0 0 0 0 0 0], t = 3, k = 3
Expected
    <int>: 55
to equal
    <int>: 60

You are given a certain array of positive and negative integers which elements occur only once (all of them different from 0)
