well, it depends how you interpret the description I guess. The description should either:

• state the exact rules, with examples
• OR tell us that it's a prerequisite that we known the rules, and link us to the proper rules somewhere online

I watched a quick guide of the rules. For instance, the statement below is incorrect. You can't flip any pieces in between, you can only flip from the piece you place to your first own piece.

A player can play only if he has a valid move. Valid moves are those in which an opposing piece is trapped (horizontally, vertically, or diagonally) between one already on the board, and the piece being placed. Any pieces between will be flipped (could be more than one!).

For instance

BWWBWW

-> if you place a B at the right, you end up with

BWWBBBB

balanced_num = balancedNum

it provides an alias to the snake_case version of the camelCase function name.

Example of function name aliasing:

p = print

p("Hello, World!")

All these ARE explained. Not spoon fed, ok, but the info are present.

I can't imagine how bad the description was before. It's still a bad description. You don't explain how we should interpret the input. You don't explain how a valid moves looks like.

It reads, "remove those two digits from the string", but then the spaces are both assumed and relevant, part of the string which never really got "smaller" (shorter). If it means "replace those two digits with spaces", and "return the minimum possible number of remaining ones and zeroes" then it should say that. Also that apparently was a question in the past, but now it's a direct instruction, and it still has a question mark.

yup, still can't make sense of it after understanding the solutions.

I've put my own solution as ref sol for the moment being. You should be able to pass Python now and check if the Python translation has any errors.

even with that fix, in Python I'm not always close enough to ref sol, while I am in JS; anyway, JS and Python updated

I updated the formula and the tolerance (js, python), but I think author solution in js and python are not the same. I give up on this kata. Let's tank it.

auhor has given up on this, I vote to retire

yes

i can't speak either

grah

probs nah
