6 years later it looks like the (current) limit of 500 is fine

ruby random tests are giving wrong values, including the country name, e.g.

"China" => "China,54,32,44"  # instead of just "54,32,44"

Quel bordel!

Now let's create a kata for B... oh, wait

That is a list of precalculated results.

I thought |n| means the absolute value of n, but fine

This is just the end of the "small" random tests, "medium" and "large" are obviously larger:

Under "large", it's even worse:

ValueError: Exceeds the limit (4300) for integer string conversion; use sys.set_int_max_str_digits() to increase the limit

kthxbye

issues:

• description says 1 ≤ ∣n∣ ≤ 10 which is wrong
• example in description says n = 11 but "Note that n will be represented as a binary string"

Fine, I just need to read more attentively ;-)

"aa"   --> ""
"aaa"  --> "a"
"aaaa" --> ""
"aabb" --> ""
etc?

Shuffling integer can result in a number that is greater than the original

My bad - looks like my mind skipped that part of the description...

update: It may be a good idea to add this to the description
