Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

You need to calculate the infinite sum (first term is n, each following term is the previous term integer-divided by 2), not just the sum of the first five terms.

Nobody's going to invalidate all solutions to test some arbitrary value.
I submitted a solution with a different signature and it works. For correctness then the instructions should indicate a max value for the expected input. Otherwise the solutions, from a production grade point of view, are incorrect.

When halving should we be rounding up, down, or to the closest integer?
Just typecast it to an integer and it should take care of it for you, depending on which language you're using
Ace, thanks!

Man if this wasn't using integer division it would have been a one liner...
( Depending on your language ) It still is.
Thanks for this kata. I think it would be a good kata if the input integer could be anything other than positive. Especially for JavaScript, because JS doesn't have native method for integer division, but the "floor" method rounds negative integers in a non-obvious way (Math.floor(-99.01) == -100).
Nobody's going to change the requirements now.

Why should 72 equal 73?
There is no fixed test in Python expecting that result, so it was a random test. Print the input to know what it is, your code was off by one.
Thank you. Solved!

Yep, it's easy to overlook.
