It is the year 2018, Russia. History repeats itself and the not-so-young football coach Niko is leading the national team in a clash with Brazil.
Choosing a formation is the first step when it comes to preparing the strategy for a football game. A formation can be represented with three integers
After choosing a formation, the coach needs to carefully choose the players because not every player is a defensive wizard or a world class striker. The coach knows his players very well. He knows which line suits each player. Setting a player in a line he doesn't know how to play would be tactical suicide.
The coach and his team of experts have put together a list of formations that can be taken into consideration against Brazil, but in all their expertise they didn't have time to determine the formations which they have suitable players for. Help them!
