Should be "teams played a draw" rather than "teams played draw". The latter is grammatically incorrect.

bit is the short form of "Binary digIT", and so a "set bit" is a binary digit whose value is 1; it's the opposite of a "cleared bit"/"unset bit" which has value 0.

It is strangley hard. I've seen a couple of 6kyu recently that are just really tough

THANK YOU VERY MUCH!!!!

Yes, too "much" letters for me. Well done for oversimplifying it into something you can understand.

Too much letters for you?

Very nice

Is the indentation of the elif statement intentional here? If so, what does it do? Would this snippet not lead to an index error due to trying to pop() from an empty list? e.g., if the first character is a '#' symbol?

Same digit at the beginning and end of binary digit

What is a set bit?

Could just be me, but this is the hardest 6kyu I've seen by a mile. I did enjoy the challenge though. Thanks for posting.

Nice one. Thanks for you reply. Clever solution

Why so many long-winded and confusing descriptions for simple katas? Could have said something like this: 'A valid string will only contain letters from a-m. Write a function that returns the number of invalid characters in the string over the number of all characters in the string. E.g., 3/56 where 3 is the number of invalid characters and 56 is the number of all characters.'

Will be skipping g964 katas in future.
