It would be more interesting to make a kata for arbitrary number of teams, not only even, so for odd number one team misses one tour...I wanted to do such kata but found this

even less

Yeeeah! Thats it, man!!! Now 84

Thanks for inspiration, your 92 characters inspired me to find 87 characters solution. May be someome will beat even this =)

This solutiom is failed with
[[16,null,null],[11,null,15],[4,null,1]]

Expected: 'null', instead got: '[[16, 0, 15], [11, 5, 15], [4, 26, 1]]'

Please check if you wish

I got it, thanks

Sorry, i'm new one here, do you mean fold the code in or press Spoiler button under the message? And if spoiler button is red does it mean that it will not appear on homepage?
