but in the first test case yellow also didnt connect but yellow wins

Test.assert_equals(who_is_winner([ "C_Yellow", "E_Red", "G_Yellow", "B_Red", "D_Yellow", "B_Red", "B_Yellow", "G_Red", "C_Yellow", "C_Red", "D_Yellow", "F_Red", "E_Yellow", "A_Red", "A_Yellow", "G_Red", "A_Yellow", "F_Red", "F_Yellow", "D_Red", "B_Yellow", "E_Red", "D_Yellow", "A_Red", "G_Yellow", "D_Red", "D_Yellow", "C_Red" ]), "Yellow")

im a little confused

Hello,

How is the last test case a draw?

(who_is_winner([
"A_Red", "B_Yellow", "A_Red", "E_Yellow", "F_Red", "G_Yellow", "A_Red", "G_Yellow"
]), "Draw");

If the game ends prematurely and no player connected 4, then we assume a draw?

How big is n?

Each \n marks the end of a row.

I'm not sure what the input is.

Why does it have a bunch of \n in it?

Thank you.

Brute force fails.

You're mutating the input.

Silly me.

a,b <= n, not sum(n)

Thanks for the quick reply. :)

I think you should read the description again. Cheers.

Some Python tests are broken.

If the correct answer is on the right, it should not contain 0s where directions had to be removed.
