Your Game#5266
The LKS Championship in "My Game" has been incredibly successful for me. I've won three qualifying rounds and advanced to the super final, where my opponents are my teacher and my best friend. After a fierce competition, we enter the final round with the following scores: my teacher has points, my friend has points, and I have points.
The rules for the final round are as follows: At the start of the round, each player places a bet. Each player can bet any positive number of points, as long as it does not exceed their current score. After all bets are placed, each player answers a single question. If a player answers correctly, their score increases by the size of their bet; otherwise, their score decreases by the same amount. The winner is the player who ends up with strictly more points than both of the others.
Is it possible for any of us to make a bet that guarantees a win, regardless of how the others answer?
The first line contains the positive integers , , and , each not exceeding .
Output Teacher if my teacher can guarantee a win, regardless of the answers of the others. Output Friend if my friend can do this, and :) if I can do it. If none of us can guarantee a win, output Nobody.
