The kata is ok, but I would rate it as 6 kyu. IMHO a little bit complicated for 7 kyu

The kata is nice, but most likely I would rate it as 5 kyu, not 6. IMHO, as 6 kyu problem, it requires too much manipulations

In Python version we need to compare the total number of bears with x and in JS version - the number of pairs with x. So, description for the JS one (saying that "whether the total number of bears is greater than or equal to x") is incorrect

The tests should necessarily include numbers from 100. Without that you can complete it and earn honor even with an incorrect solution

Sometimes it's possible to pass through all the tests even with a incorrect solution. I'm taking about this edge case:
"There may be more than one answer, i.e. two or more integers produce the longest Collatz sequence, because they happen to have sequences of the same length. In this case, your function should return the integer that appears first in the array."

IMHO This kate is a little bit complicated for 6 kyu. Most likely I would rate it as 5 kyu

OOP tag might be added to this kata

The kata is nice, but maybe 6 kyu rate will be more appropriate for this one. And also I think that adding the OOP tag would be useful

The kata is nice. I suggest to add OOP tag to its description

There is a typo in test cases: "Briish" instead of "British" ("Not a Briish prefix")

I would rate this kata as 6 kyu rather than 7, but it's nice anyway

Nice kata, but most likely I would rate it as 6 kyu rather than 7

Kata is ok, but in my opinion it's a little bit complicated for 7 kyu. 6 kyu would be better

The kata is ok, but I would rate this kate as 6 kiy rather than 7

La kata (o el kata?) es muy buena! Aprendo Espanol
